The Portuguese is preparing his team for Thursday’s game at Feyenoord and is disappointed that the stadium’s capacity will be reduced because of crowd trouble.
Speaking at his news conference on Wednesday, Mourinho said: “This is not a competition that Man United wants. It’s not the big dream of every big player, but we are not in the Champions League.
“We come to win the game. We want to win the competition. It’s difficult to do, but it’s simple to feel it and to say. This is the way we want to approach the competition.
“For a club of our dimension, to do well is not to be out in the group phase. Tomorrow is an important match for us.”
