Manchester United boss Jose Mourinho has called for unity ahead of their Champions League clash with Valencia.

Mourinho spoke to the press on Monday in which he questioned the fight of some of his players.

"The reason why we don't win matches is the same as why we win matches," continued Mourinho. "It's down to everybody. The performance on the pitch is down to many factors."

He added: "I see different reactions, but sometimes what you see is different from the inside. You see some people on the outside look like they haven't lost a game, but in training they are working hard."
