Manchester United manager Jose Mourinho admits he's upset with Andreas Pereira.
The midfielder left United last week to join Valencia on a season-long loan.
"Andreas Pereira was a personal decision that I don't agree with," Mourinho said. "A decision I don't think honestly I don't think is the best decision for him, a decision that disappoints me a little bit, because I think he has the potential to be here fighting for a position, for opportunities, and fighting to be a Manchester United player.
"I think his decision can be considered a decision of a young player who wants to play every weekend but can also be considered a decision by a young player that is not ready to fight for something difficult and it's difficult to play in the Manchester United midfield.
"You have to be ready to fight for a position and I am a bit disappointed that he left. But okay, it was his decision, I open the door for his decision, he has a long-term contract, we have the option to bring him back on January 1, so we have that situation under control. It is not a drama but is a decision that disappoints me a little bit."
