The former England midfielder, 36, who joined United from Tottenham in 2006, will take on a role among Mourinho's back-room staff this summer but admitted his ultimate aim is to become a manager in the future. It was Mourinho that brought him to Madrid in the first place, so the Man Utd boss may have an advantage when trying to persuade him to leave.
'You know, if I listened to everyone, I would be everywhere'.
"I think our team this season have shown that on certain days they can turn up, as they did against City and at Wembley against Spurs".
Mourinho insisted there was simply "no chance" that the reported Real Madrid target would depart.
And if Mourinho gets his way, he could be heading to Manchester United over in the summer in a player-plus-cash deal.
But despite French champions Paris Saint-Germain reportedly being prepared to launch a bid for the 25-year-old, Mourinho told a news conference on Wednesday: "I think he is going to be here next season".
Mourinho's side only need a point from their last two league games to confirm finishing second this season, but the title has looked out of their reach since December.
We'll file this one in the "we'll be keeping an eye on this" section of our archives, mostly because it's Le10 and we don't recommend getting excited about anything they say.
Mourinho was scathing of his players afterwards, having presented the likes of Anthony Martial and Marcus Rashford with opportunities to stake their claims for starting berths in the absence of Romelu Lukaku and Alexis Sanchez ahead of the FA Cup final against Chelsea.
"What does he need to do to impress me?"
"So in this moment, for me, he's staying, yes". "Football is not full of them, society is not full of them, so when you find one of them, you have to value them".
"I am not afraid to play against the big teams and I respect the small teams, and I prepare a match against a big team in the same way I prepare a match against a small team". Unless you can do that, and you go in the direction of the ideal squad, you have to keep players you don't love.
