Real Madrid boss Mourinho surprised Carvalho stayed
Carvalho appeared on his way to QPR in August.
"I thought he wanted out of Madrid, he is a tremendous player - especially for me, as I have had him at three clubs," Mou said.
"With his injury last season and with Pepe and Ramos forming a partnership which can be the best in the world, he got a little delayed.
"But he decided to stay in Madrid, for me it is not a problem, he could be a solution but he knows his chances could be restricted."
