Sneijder faces his old club in tonight's Champions League quarterfinal first-leg.
He told Marca: "Listen, there are things about Mourinho in the press every day which don't necessarily need to be true. I don't know if he's going to leave to be honest. In my personal opinion, it would seem very strange to me that he would leave already, so quickly.
"The work that Mourinho's doing at Real Madrid is perfect.
"He won the league last season, they've always gone far in the Champions League, this season they are still fighting to win it. I think his job is there, isn't it?"
