Manchester United winger Antonio Valencia has explained why he has taken back the number 25 shirt for this season.

The 28-year-old wore number seven last season but is pulling on his original number this campaign.

"I think it turned out to be a very good number for me when I first arrived at the club as I was just given the no. 25 more or less," he told MUTV. "But things went really, really well. I played well wearing that shirt so I think it was a decision I came to in the summer.

"Maybe if I can get back to the form I showed before, why not? It is a good idea to start wearing it again. It had been something I had been thinking about for quite a long time.

"I'd been considering a change back and maybe it is psychological or maybe it is just all about a good-luck symbol, if you like. We get a lot of that in Ecuador, maybe superstition, and l hope it continues and still brings me more good luck this season."

United will take on Manchester City in the derby on Sunday.
