Mourinho has tipped the man he tried desperately to sign last summer to shine at the World Cup despite an underwhelming build-up.
"He is in the best age. It's his World Cup. He also has a role as leader in the team, a little bit similar to the role he had at United this season. I think he is ready to cope with this pressure.
"Maybe the fact that the season was not good in the club can also play a positive role, a role of someone that is a natural winner who normally every season wins something.
"The fact that he won nothing this season can play a positive role. His ambition and his hunger to succeed. I have faith in him that he can do it."
