Manchester United winger Antonio Valencia admits injury has affected his form this season.

The Ecuador favourite concedes he hasn't been at his best this season.

Valencia told MUTV: "I think when you've suffered a couple of injuries, sometimes it's hard to get back to those fitness levels where you can play full of confidence and you can show your ability in its best light. Sometimes it takes a while if the recovery from injury is longer than you think. It's hard to get back to top form and the rhythm of how you normally play but hopefully pre-season will be a chance to get fit.

"When things are not going particularly well and when I'm not on my best form, I tend to be a bit harder on myself because, all the time, I want everything to turn out perfectly. So you do think about your form at these times."
