When do Champions League teams go to the Europa League?
The 2016 Europa League winners Sevilla were originally in the Champions League and this has become a familiar trend.
For the 2016-2017 Europa League campaign, the teams finishing 3rd in their Champions League group will enter the Europa League at the last-32 stage.
This means bigger teams come in and they are often among the favourites to go all the way. It also throws up some fantastic matches - much like Liverpool vs Borussia Dortmund last season!
