Sir Alex Ferguson believes that Wayne Rooney will rekindle his goalscoring form in due course of time as most players rely on their confidence to find the back of the net. The former Everton man has only one goal this season and his failure to live up to expectations has led to growing concerns in the United management.

Louis van Gaal has changed his system to accommodate Rooney, with the striker now playing behind Anthony Martial, who is in top form. The France international has scored three Premier league goals so far and has been a revelation since coming to Old Trafford from Monaco this season.

Rooney has spent 10 years at the club, and is among the few players at Old Trafford, who have played under Sir Alex Ferguson. Therefore, his former manager has insisted that the blip is temporary and all greats, including Eric Cantona, Ruud van Nistelrooy and Andy Cole had that silver streak going for them after a barren spell.

"All the strikers I had, everyone relied on their confidence," Ferguson told ESPN. "When they were scoring they think they can never stop, when they're not scoring they think they're never going get a goal, it's a fact.

"When I was a striker I was the same; my dad used to say make sure you hit the ball, don't try and pass it in the net. Eric Cantona had it, [Ruud] van Nistelrooy had it, [Andy] Cole had it and then the rich stream comes along again and they're back to normal. I think we'll have to wait, it'll happen. [Rooney will] go on a run, don't worry about that," he added.

The forward sat out of the international break with an injury, but should be available for selection when United face Everton at the Goodison Park this Saturday. The Red Devils need to put in a valiant performance, following a 3-0 drubbing at the hands of Arsenal, in their last game in the Premier League at the Emirates.
