Iker Casillas claims that Cristiano Ronaldo is concerned with his injury that seems to be getting worse.

The talented Portuguese winger was supposed to have recovered this week and return to training for Real Madrid but it now seems that he may have to consider surgery to repair a troublesome ankle.

Speaking to the Marca, Casillas said: "Cristiano is concerned because he thought he would recover this week, and play some minutes against Alcorcon [in the Copa del Rey second leg],

"We hope now that he improves, as we need to see him back with us and scoring goals again."

Casillas went on to plead for everyone to remain calm and give Madrid more time to gel.

He continued, "The team are working well. We are a new group, and we must take a little longer to integrate. It is normal for the fans to demand things, it is their right, but we must remain calm.

"It will be a derby with two teams in different situations. We're not complacent. We want the three points,"

Casillas and his teammates will have their work cut out this weekend as they take on city rivals, Atletico in the Madrid derby.
