Liverpool boss Rafa Benitez is delighted with the form of new signing David Ngog in preseason.

"David is a young player but we knew when we signed him that he had a lot of ability and a lot of potential," Benitez told liverpoolfc.tv.

"It can sometimes be difficult for young players when they move to a new club, but he has done well and it will be good for his confidence that he has already scored two goals.

"It is now important that he keeps on working hard and trying to get better because he still needs to improve. I think that he will do that.

"His goals are positive but equally important is his movement because this shows that he has game intelligence which was one of the main reasons why we brought him to Liverpool."
