Liverpool captain Steven Gerrard believes Jordan Henderson can one day succeed him as the driving force in the Reds midfield.
England international Henderson, 20, completed his £20m move from Sunderland to Anfield on Thursday.
"It's a really positive signing. Let's hope he is the next Steven Gerrard," he told the Liverpool website.
"Good football clubs replace their best players. Liverpool need a new Gerrard and need a new Jamie Carragher."
Gerrard, 31, has spent his entire playing career at Liverpool, having signed his first professional contract in 1997, and has won the league cup and FA Cup twice, the 2001 Uefa Cup and the 2005 Champions League with the club.
Henderson will have to compete with Gerrard, Lucas Leiva, Jay Spearing, Raul Meireles and Christian Poulsen for a place in the Liverpool midfield.
He added: "I saw Jordan at first hand for two or three days with England and he is a good player with energy."
Meanwhile, Gerrard, who missed the end of last season after undergoing groin surgery, says he is battling to be fit for the start of the season.
He said: "I have confidence in what I can do. I am going to be in the best condition physically going into this season that I have been for the last 10 years.
"I am working doubly hard on my body, on my core and on strengthening my groin, which I have suffered with.
"The operation went well and I have nearly double the strength in the groin now than before. The physios at Liverpool are measuring that on a weekly basis and the results show that.
"I know I will be rusty in friendlies but I have confidence that I am going to be the freshest I have been, both mentally and physically, for a long, long time."
