This should be a fantastic couple of matches. Both teams will fancy their chances of progressing to Wembley and although Liverpool are the favourites - nothing can be ruled out. After all, they have made a poor habit of losing against teams they are expected to beat comfortably.
Southampton then know the first-leg is where they need to do the damage. If they get a result in front of the home fans on Wednesday night, perhaps they have a chance going to Anfield for the second-leg.
Who are you backing?
