Mourinho told talkSPORT: “He's the kind of player that you expect to finish his career at Real Madrid.
“It is quite surprising that it didn't happen.
“In spite of his injuries this season that kept him out for a couple of months and even the decision of Luis Enrique to leave him out of the Euros, that doesn't hide the fact he is still a very good player, capable of performing for a couple more seasons at a very good level.
“I can imagine we will see him playing in a very good club.
“Only a top club will be in a condition to fulfil his financial demands."
Mourinho added: “Look to Thiago Silva – he is in a similar situation.
“He came to Chelsea, didn't play every match, had a couple of little muscular issues, but in big matches he gave great stability and you can imagine how much he helped the team to develop, the young players, the leadership.
“Ramos is in a similar situation. He is even more physical than Thiago to compete with the Premier League demands.
“I have no doubt he can play with intensity and the demands of the Premier League. No doubts."
