NK Celje welcome AEK Athens to Arena Petrol on Thursday 12 March 2026 (kick-off 20:00 GMT) in what promises to be a pivotal UEFA Conference League knockout round encounter. The Slovenian champions face a daunting task against one of Greece’s most storied clubs, but Arena Petrol has proved a fortress in European competition this season and Celje’s tenacious style can make life uncomfortable for any visiting side. AEK Athens, under the guidance of manager Marko Nikolić, arrive carrying the weight of expectation from a passionate support base — and with individual quality throughout the squad that should, on paper, prove too much for the Slovenian outfit. However, knockout football is anything but predictable, and Celje’s organisation and determination could yet spring a surprise. Read on for our full team news analysis, key player focus, head-to-head breakdown, and best bets for tonight’s Conference League clash.
| Market | Prediction | Confidence | Reasoning |
|---|---|---|---|
| Match Result | AEK Athens Win | ⭐⭐⭐⭐ | AEK Athens are heavy favourites at 4/7 with multiple bookmakers; Celje’s home form in European competition has been commendable but their squad depth is far below that of the Greek giants |
| Both Teams to Score | Yes | ⭐⭐⭐ | Celje have shown they are capable of troubling European opponents at home — Ivan Maevskiy’s side possess legitimate attacking threats in Rudi Požeg Vancaš and Matej Poplatnik, making a Celje goal realistic even in defeat |
| Over/Under 2.5 Goals | Under 2.5 | ⭐⭐⭐ | AEK Athens are disciplined defensively under Nikolić and Celje will likely set up with a compact defensive shape; a tight, low-scoring contest is the more likely scenario in a high-stakes knockout tie |
| AEK Athens to Win to Nil | No | ⭐⭐⭐ | Celje have the attackers to trouble AEK — a completely clean sheet for the visitors is not guaranteed given Celje’s home record in Europe this season |
This Conference League knockout round tie represents the pinnacle of NK Celje’s recent European adventure. The Slovenian Prva Liga champions have navigated through qualifying rounds and the league phase to reach this stage, an extraordinary achievement for a club from a nation whose domestic football rarely commands continental attention. Arena Petrol, situated in the industrial city of Celje in central Slovenia, holds just over 8,000 supporters — but on European nights it generates an atmosphere that has visibly unsettled visiting sides throughout this campaign.
For AEK Athens, the UEFA Conference League represents an important vehicle for silverware and European prestige. The Athens giants, one of the ‘Big Three’ clubs in Greek football alongside Olympiacos and Panathinaikos, have a rich continental history and manager Marko Nikolić will have identified this competition as a genuine opportunity to deliver European glory to the OPAP Arena faithful. Nikolić, the Serbian tactician, has brought a disciplined, tactically astute approach to the Athens club, blending experienced international stars with technically gifted Greek players. A side containing Luka Jović, Roberto Pereyra, Razvan Marin and Marko Grujić represents significant pedigree at this level, and AEK will be confident of advancing.
However, the two-legged nature of knockout ties always contains an element of jeopardy — particularly when one leg is played on a tight, charged pitch in front of a partisan crowd. Celje know that keeping the deficit to a minimum, or better still snatching an away goal on their own turf, could have profound implications for the return leg in Athens.

NK Celje head into this tie under manager Ivan Maevskiy, the Belarusian coach who has guided the club through their impressive European campaign this season. Maevskiy’s side are compact, hard-working and difficult to break down — qualities that have served them well against more fancied opposition throughout this Conference League run.
In goal, Simon Sluga is likely to start between the sticks. The experienced Slovenian shot-stopper has been a key figure in Celje’s journey and will need to produce a standout performance to keep Jović and company at bay. The defence in front of him is well organised. Žan Karničnik offers pace and defensive solidity at the back, while Łukasz Bejger brings Polish league experience to the defensive unit. Damjan Vukliševič and Juanjo Nieto Zarzoso complete a defensive line that has demonstrated resilience over the course of the competition.
In midfield, Mario Kvesić is Celje’s creative fulcrum. The former Croatian international brings technical quality and an eye for a pass that elevates Celje’s play beyond what many opponents expect from a Slovenian club. Alongside him, Tilen Letonja provides energy and pressing intensity, while Mark Zabukovnik adds physicality and work rate. The midfield trio will need to be at their collective best to limit the creative supply lines of Pereyra, Marin and Grujić.
Up front, Celje’s attacking threat is led by Rudi Požeg Vancaš, who has been directly involved in multiple goals during this European run. His movement off the ball and ability to link play are vital to how Celje transition from defence to attack. Matej Poplatnik offers a different option — more direct and willing to run in behind — while Armandas Kučys and Nikita Iosifov can provide impact from the bench. Celje are unlikely to commit men forward recklessly given the quality of AEK’s counter-attacking weapons, but they will back themselves to create at least one genuine chance on their own patch.
The home crowd will be another key weapon in Celje’s armoury. Arena Petrol’s compact nature means the pitch and the atmosphere can be hostile for visiting teams unaccustomed to these conditions, and Maevskiy will look to harness every advantage available to him in this first leg.
Manager Marko Nikolić has assembled a squad of considerable depth and international pedigree at AEK Athens. The Serbian coach, well regarded across European football, has instilled a clear tactical identity — pressing high when the opportunity presents, maintaining structural discipline without the ball, and using technical quality to control matches when in possession.
Between the posts, Thomas Strakosha provides commanding presence and assured shot-stopping. The Albanian international goalkeeper, previously of Lazio and Brentford, is no stranger to European occasions and his experience will prove invaluable in what promises to be a testing evening in Slovenia.
Defensively, Domagoj Vida brings a wealth of experience. The Croatian international — a World Cup finalist with Croatia in 2018 — marshals the backline with authority. Harold Moukoudi adds physicality to the defensive unit, while James Penrice and Alexander Callens provide coverage across the full-back positions. Filipe Relvas and Stavros Pilios offer further defensive options from the bench.
The midfield department is where AEK truly flex their quality. Razvan Marin, the Romanian international, is one of the most technically accomplished central midfielders in Greek football and his ability to dictate tempo makes him central to everything AEK do in possession. Alongside him, Marko Grujić brings box-to-box power and the ability to arrive late into attacking positions. Roberto Pereyra — the experienced Argentine, formerly of Juventus, Watford and Udinese — provides creativity and dynamism from a wider position, and his ability to beat his man and create chances is one of the key threats Celje must manage. Hakim Sahabo, Orbelín Pineda and Robert Ljubičić offer rotation options across the midfield.
In attack, all eyes will fall on Luka Jović. The Serbian striker, who has represented Real Madrid and AC Milan at the peak of his powers, is exactly the type of finisher who can punish any defensive lapse. Jović’s movement in the box and finishing instinct make him a constant danger, and Celje will need Sluga and the defensive unit to be at their absolute sharpest. Barnabás Varga offers an alternative profile — the Hungarian forward is powerful, dangerous from set-pieces and willing to work the defensive line. A. Koïta provides further options from wide areas, and AEK have more than enough firepower to win this game convincingly if they play to their potential.
Luka Jović (AEK Athens) — The Serbian striker needs no introduction. Despite the journeyman nature of his career in recent years, Jović remains a natural goalscorer with sharp movement and proven ability to finish at the highest level. In the context of this Conference League tie, his quality is simply on a different level to most strikers Celje will have faced this campaign. If AEK create chances — and they should — Jović has the composure and technique to take them.
Roberto Pereyra (AEK Athens) — The veteran Argentine midfielder is the kind of player who makes those around him better. His ability to carry the ball, play incisive passes and arrive in dangerous positions late makes him the orchestrator of AEK’s best attacking play. Celje’s midfield will be tasked with limiting his influence, a task easier said than done against a player of his pedigree.
Rudi Požeg Vancaš (Celje) — Celje’s chief attacking threat and the player most likely to give AEK’s defence a problem. His movement and finishing ability represent the clearest route to a home goal, and if Celje are to cause an upset or keep the tie alive heading to the return leg, Požeg Vancaš will almost certainly need to be involved. The pressure on the Slovenian forward tonight is significant, but so too is the opportunity.
Mario Kvesić (Celje) — The creative heartbeat of Celje’s midfield. The experienced Croatian midfielder brings a level of technical ability that is unusual in domestic Slovenian football, and his work rate and vision will be central to any Celje success. If Kvesić can find pockets of space against AEK’s midfield press, he has the quality to exploit them.
Razvan Marin (AEK Athens) — The Romanian international is one of the more underappreciated midfielders in this competition. Marin’s range of passing and his ability to control tempo will be crucial in managing this game the way Nikolić wants. A dominant performance from Marin typically means AEK win comfortably — his form is one of the key indicators of AEK’s overall performance level.
Maevskiy will almost certainly set Celje up in a low-to-mid defensive block, looking to deny AEK space in behind and force them to try to break down a disciplined structure. The Slovenian side are not short of quality in transition, however, and counter-attacking opportunities through Požeg Vancaš and Poplatnik will represent their primary route to goal. Celje’s press in the middle third can also be effective in disrupting opponents who are expecting an easy passage through the lines.
Nikolić’s AEK will look to dominate possession and build patiently through Marin and Grujić in midfield. They will test Celje with movement from Jović and width from Pereyra and Koïta, seeking to stretch the Slovenian defensive block. Set-pieces will also be a weapon — Varga and Vida are both threats from corners and free-kicks. The key tactical question is whether AEK can break down a well-organised Celje rearguard without leaving themselves exposed on the counter, which remains the primary risk in away legs against compact European opposition.

AEK Athens are clear favourites across all bookmakers with available odds. The best price on a Celje win is 4/1 with Paddy Power, Betfred and AKBets — reflecting the Slovenian side’s underdog status but also acknowledging the genuine possibility of an upset at a tight Arena Petrol. The draw is priced around 14/5 with the majority of bookmakers, while AEK Athens’ best odds are 4/6 with AKBets, slightly ahead of the 4/7 available elsewhere. For those backing the Greek giants, AKBets offers the most attractive return on the away win.
The most interesting betting angle in this match is the Celje home win at 4/1. While the Slovenian side are clear underdogs on paper, the reality of European knockout football at a compact ground like Arena Petrol means upsets are never far away. If Celje are well-organised and clinical on the break — two qualities they have demonstrated throughout this European campaign — a home win is absolutely within the realm of possibility. This is not a bet to place in isolation, but as part of an accumulator it represents genuine value against a team that, despite their quality, will be playing on unfamiliar territory against a fired-up home side.
The AEK Athens win at 4/7 or 8/13 is the banker selection for most bettors, and it is hard to argue against it given the quality of Nikolić’s squad. However, the price is short enough that it only makes sense as part of a combination bet or if you add a goalscorer or correct score market to the selection to boost the odds.

BTTS Yes is the favourite with the majority of bookmakers — priced between 8/13 (Paddy Power) and 8/11 (Betfred, AKBets). The market reflects a genuine expectation that Celje will find the net at least once, even in defeat. Betfred’s 8/11 on BTTS Yes represents the best value in this market. For those who prefer BTTS No, the 11/10 available with Paddy Power, Sky Bet and AKBets is the standout price — this market reflects the possibility of AEK keeping a clean sheet if they control the game from the outset.
Live Over/Under 2.5 Goals odds were not available from our data feed at the time of publication, but the market dynamics are worth analysing. Given the tactical profile of both sides — AEK Athens’ disciplined, patient build-up play and Celje’s compact defensive structure — a low-scoring contest is the more likely outcome. Both sides will be conscious of the second leg implications, making reckless attacking play unlikely. Under 2.5 Goals aligns with both the implied probability of AEK Athens winning narrowly and the home side’s likely setup. We lean towards Under 2.5 as a supplementary selection, though we advise checking live odds on your preferred bookmaker before placing any bet on this market.
Celje and AEK Athens have not met previously in European competition, making this a genuine unknown quantity from a historical perspective. Celje’s European record at Arena Petrol this season has been their strongest argument for an upset — the Slovenians have taken points off opponents who were expected to win comfortably, and their home support creates a genuine psychological barrier for visiting teams. However, the gap in squad quality and resources between the two clubs is substantial. AEK Athens, backed by the resources and expectation of one of the biggest clubs in Greece, will be targeting progression from this round as a minimum objective.
In terms of European pedigree, AEK Athens have competed regularly in European competition over several decades and their squad contains players who have been at the highest levels of the game — Luka Jović’s Champions League experience, Roberto Pereyra’s years at Juventus and in the Premier League, Domagoj Vida’s World Cup experience. These are players who do not freeze on European nights. Celje, by contrast, are making their deepest run into European competition in the club’s history, which is a remarkable achievement but also comes with inexperience at this stage of knockout competition.
Arena Petrol in Celje will be packed to its 8,000 capacity on Thursday evening, and the atmosphere generated by the home support will be a tangible factor. European nights at smaller grounds in Eastern Europe have a unique intensity that larger stadium atmospheres sometimes fail to replicate. The pitch at Arena Petrol is well maintained and the playing surface should suit both sides’ preferred styles of play. Weather in Slovenia in mid-March can be unpredictable — cool temperatures and the possibility of rain could make conditions slippery and potentially favour a more direct, physical approach.
This is a game where the quality differential between the two squads points clearly in one direction, but the context of a compact European away fixture gives Celje a genuine platform to make this tie competitive. Our primary selection is AEK Athens to Win at 4/7 (Sky Bet, Paddy Power) or 4/6 (AKBets) — Marko Nikolić’s side have too much quality throughout the squad for the Slovenian champions to cope with over 90 minutes. Luka Jović, Roberto Pereyra and Razvan Marin collectively represent a level of technical and tactical quality that Celje simply cannot match on a consistent basis.
For those seeking additional value, Both Teams to Score — Yes at 8/11 (Betfred or AKBets) is our supplementary selection. Celje’s attacking players — particularly Rudi Požeg Vancaš — are capable of troubling any defence at Arena Petrol, and we expect the home side to fashion at least one clear opportunity. AEK’s own attacking quality means they should score as well, making the BTTS Yes a solid combination with the away win.
Our betting summary for Celje vs AEK Athens: AEK Athens Win + Both Teams to Score Yes — a combination that reflects both the likely outcome and the probable goal pattern of this Conference League tie. Kick-off is at 20:00 GMT at Arena Petrol, Celje. As always, please gamble responsibly and within your means.
