Manchester United have sold Netherlands forward Memphis Depay to French Ligue 1 club Lyon.
It is thought the fee is £16m rising to £21.7m, with the add-ons including Lyon qualifying for the Champions League and the 22 year old getting a new contract.
United have also agreed buy-back and sell-on clauses.
"From my perspective, instead of trying to say why it didn't work, I think it is easier for me - and he deserves me to say - that he was a fantastic professional," said boss Jose Mourinho.
"So if somebody thinks it didn't work because he was not a great professional, it is totally wrong.
"One thing is some picture that somebody takes with him in an amazing car or dressing in a very specific way, but the image is totally wrong.
"The guy is a fantastic professional, he is a kid that respected everyone, a kid that tried to work hard to get more chances, a kid that was frustrated because he was not having that, but I only have good things to say about him."
He added: "If I can find a little reason, it is to say he is a player from one position and the only position where we have overbooking. Wingers are what we have more of, so it is a position more difficult to have chances."
