Louis van Gaal has blasted the "unbelievably stupid" Marouane Fellaini for his red card in Manchester United's 0-0 draw at Hull City on Sunday.
The Belgian midfielder was sent off less than 20 minutes after coming on following a rash challenge on Paul McShane in United's end-of-season clash at the KC Stadium.
"Fellaini doesn't want to do that. For him, it is unbelievably stupid," he told reporters.
"Next season he starts on the tribune and also in preparation you start more or less as a substitute, so it is not so good for him personally.
"But I don't know if that is a red card. I cannot see that from the bench but when I see it takes seven minutes, I believe, the player was not capable of standing up, it was a worst tackle."
The result was inconsequential for the Red Devils, who had already achieved a top-four finish, but a point was not enough to keep Hull in the Premier League.
Van Gaal's side finished the campaign in fourth.
