Carlo Ancelotti reveals Sergio Ramos injury

Real Madrid boss Carlo Ancelotti has revealed that Sergio Ramos is suffering with a slight knee injury.

The right-back could miss Madrid's Copa del Rey quarter-final against Espanyol on Tuesday after picking up the knock in the 5-0 win over Real Betis at the weekend.

"Ramos is in good physical shape and is very focused. He understands that we need his quality on the pitch," he told reporters at a press conference on Monday.

"He had a problem in his knee in the match against Real Betis, but we'll see tomorrow. At this moment in time, he doesn't feel so comfortable. If he improves he'll play, if not he'll be rested."

Madrid have kept five clean sheets in their last five games.
