Schwein's problem is the manager doesn't see him as part of the squad. He's openly said that Schwein is way down the pecking order, so much so that he's not even included him in the Europa squad, the competition in which fringe players have the best chance of featuring. We may find Fellaini starting ahead of anyone perplexing but the fact is Schwein is behind him, Carrick, Pogba, Herrera and Schnei so he is not going to play much if at all. Still, he chose to stay, which is his right but I would expect someone with his track record and bank balance to have more pride when the manager has made it clear that he's not in his plans, even for a low priority tournament.
