Crystal Palace's Wilfried Zaha is facing a race against time to be fit for the FA Cup final with his former club Manchester United.

"Wilf still has a problem that will still keep him out for this weekend," said boss Alan Pardew. "Hopefully he'll be okay for the final. Wilf's a naturally fit guy.

"He actually did the injury before the semi-final. We scanned him on the Monday afterwards and saw there's a slight tear there. We can't take a risk with him, it really is about risk his injury. There's no way he can play this weekend, he could possibly play at Southampton.

"He'll be vulnerable if he plays at Southampton and he'll be vulnerable if he plays in the final. The problem's high up in his attachment to his hamstring, so it's not his hamstring but it's high up on the tendon there."
