Manchester United assistant manager Ryan Giggs has backed Angel di Maria to inspire the Reds in the last few months of the season.

The Argentine made an excellent start to his United career after joining from Real Madrid last summer, but his form has been disappointing in recent months.

Giggs, however, has played down claims that the £60m signing is suffering from a lack of confidence.

"I think his confidence is fine," Giggs told Press Association Sport. "He's a quality player and we'll be looking for him to produce because it is big game after big game now. Players get used to different leagues, sometimes quickly and sometimes it takes a bit of time.

"He had a really good start to the season but with players who take risks and who can win games it's always difficult to be consistent because they will try things that other players won't do. They're capable of doing that and that's why they're match-winners and the best players."
