France youth boss Franc Rabat has criticised new Liverpool signing David Ngog for quitting PSG.

"David's choice is a more economic one than a sport one," Rabat told France-Football. "He won't be given a lot of time to play. He will have to fight to impose himself. Him leaving PSG so young is a shame.

"He has been lacking self-confidence for a year now and he didn't score a lot. Pauleta's departure offered him a chance to play his part, but he had some bad experiences.

"For example he was not part of the squad for the Coupe de France final, I think this hurt him.

"He was ahead compared to the other players when he was 16, 17 years of age, but now…

"He grew up a lot in a short space of time and has had lots of physical and muscular problems that slowed him down.

"And don't forget that a certain Fernando Torres will be above him."
