Former Newcastle defender Jean Alain Boumsong helped persuade David Ngog to join Liverpool.
Boumsong endured a difficult time on Tyneside and eventually packed his bags for Juventus.
However, he still believes the Premier League is among the best in the world and was adamant that his teenage cousin should take the opportunity awarded to him.
Ngog had been struggling for first-team opportunities at Paris St Germain, but has already made an impact on the Anfield faithful after a number of promising substitute showings.
"When he talked to me about Liverpool, I first wanted to know whether he had spoken with Rafa Benitez and whether he wanted him," Boumsong told L'Equipe.
"Then I told him that Benitez is a great coach. When he has promising youngsters he gives them opportunities and if you work hard you will get your chance.
"To me the English league is the most difficult, but David has joined it as a complete unknown and that will help.
"He will have to get more power in his game. He is still young, but has plenty of areas to improve.
"However, when he sees (Steven) Gerrard diving into tackles and (Jamie) Carragher clattering him in training, he will soon wake-up."
Meanwhile, Liverpool have signed 17-year-old Hungarian midfielder Zsolt Poloskei on a season-long loan from MTK Budapest.
