Mourinho was asked about reports that Diarra wants to leave Real this month.
"I do not know if this is so," replied the Special One. "Lassana is a player I like. If he played from the start against Getafe, it was because he is a player I like and is useful.
"But my philosophy is that every player has a price and if a player wants to leave, he pays and leaves. And if you do not pay, then he must be with us the next day to train."
