Chelsea winger Victor Moses admits they're wary of a backlash from Wayne Rooney ahead of today's FA Cup tie at Manchester United.

Rooney was axed for United's Champions League defeat to Real Madrid last week.

Moses said: "It won't be easy because United are a great side and they will want to win the FA Cup, especially after what happened against Madrid.

"Whenever I have played against Rooney, he has caused problems for defenders. He is strong and scores goals for fun."
