Barcelona midfielder Xavi believes that Real Madrid captain Iker Casillas will be missed by Los Blancos after being ruled out due to injury.
The stopper broke a bone in his thumb during Madrid's recent Copa del Rey clash with Valencia and will be out for six-eight weeks.
"It's one more problem for them, he is the heart and soul of Real Madrid and their captain. He's a huge loss for Madrid and for Spain,” he told reporters.
Regarding the controversial decision by Jose Mourinho to leave him out of the team for a few games, he added, "I speak with him a lot, we send each other messages. I sent him my best wishes as soon as he was left out of the Madrid team; I was taken by surprise by that.
"It was a shock to me that a player who has spent so many years as the No.1 and who was always in the team could suddenly be left out, but that's their problem.
“It's a complicated situation, and it's not for me to give my opinion on. I read the news and I can see that the club is not in the best shape at an institutional level.
"But they will be very difficult opponents in the (Copa del Rey) semi-finals and it will be very for us to beat them."
