Atletico Madrid coach Diego Simeone isn't surprised by Real Madrid captain Iker Casillas' revival.

The two teams meet in the Copa del Rey tonight.

Simeone said: "Several months ago I pointed out that Casillas was the best at Madrid and many laughed.

"But he has recovered his starting berth, he is a goalkeeper who has a great history at the club and he has always had great results against Atlético. Keylor Navas is a great goalkeeper, he is doing well and he will need to establish his class."
