Antonio Adan is now available after serving his two match ban.
"I liked the way Iker played against Celta. He did what a goalkeeper has to do, which is give his team points, although in that case it was a cup match," said Mourinho.
"He made the saves in the moments of truth and helped his team with his passing. He did the job of a goalkeeper of a big team. He hardly touched the ball against Osasuna, but it can be said that in these two matches the team has been good defensively and he has been part of the team's defensive play. It is too early to say whether he will play against Valencia."
