Ngog praised

The French striker has scored in Liverpool's last two pre-season friendlies and his performances have been praised by the boss.

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

"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."
