Manchester United defender Jonny Evans says an FA Cup semi with Manchester City is enough motivation going into their replay at Chelsea.

City defeated United in their 2011 semi-final before winning the first major trophy in 35 years with victory over Stoke in the final.

"We know if we get through, we've got Manchester City who beat us in a semi-final a couple of years ago," Evans told FATV. "So it will be nice to go back down there and avenge that defeat.

"We want to get back to Wembley and make a habit of it really."
