Man Utd boss Ferguson unhappy with Stoke striker Crouch
Crouch caused problems for United throughout the contest and Ferguson suggested the tall frontman was getting away with committing infringements.
Ferguson said: "He fouls all the time. He gets off with it because of his height but he jumps on top of defenders all the time.
"He has been doing that for a long time. Referees know that. Even with the goal he has maybe caught Phil Jones, but he is right above him.
"He is a handful in the air, there is no doubt about that."
