Real Madrid legend Iker Casillas is facing a difficult situation at Porto, says Portuguese legend Paulo Futre.
The Spanish keeper has made the headlines after being suddenly dropped for Porto' last two matches - against Leipzig in the Champions League and Pacos Ferreira in the league.
Futre explained: "Porto have been defending well. In don't think there's been any technical or tactical problems that would force the coach to drop Casillas. I think it's a disciplinary issue.
"Something happened with a mobile phone after a Champions League game. The coach has a very strong character and if Casillas has crossed him, he won't forgive him. I think it's going to be difficult to sort the situation out, at least for the time being.
"While the team is winning, it will be hard for him to win his place back. We'll see if he leaves in the winter transfer window but I can't see that happening to be honest."
