Gerrard played alongside the 20-year-old midfielder with the senior England squad against France last November, and feels he has shown enough to prove he has a lot to offer the club.
Gerrard said: 'It's a really positive signing. Let's hope he is the next Steven Gerrard. That's what good football clubs do - they replace their best players. Liverpool needs a new Gerrard and it will need a new Jamie Carragher.

'I saw Jordan at first hand for two or three days with England and he is a good player with energy.'
After three months on the sidelines Gerrard has also announced he is fit, raring to go and ready to help Kenny Dalglish's on-going revolution at Anfield starting next season.
Gerrard had to sit out the closing stages of the Red's season, following a traumatic training ground injury which left him requiring surgery on his damaged groin.

'I am excited about playing under Kenny Dalglish, just like the team did at the end of the season, which was going forward. We were playing with bottle and character and going all out to beat teams. And that always suits my style of playing.'
Liverpool were just pipped to fifth place by Tottenham who took the Europa League berth for next term, but Gerrard, who has been undergoing intensive physiotherapy, is hopeful the club can push on to greater things.
'For two or three hours each day I will have to work on my body to make sure I am right,' said Gerrard, who turned 31 last month. 'But I don't see that as a chore. This is me getting right for Liverpool Football Club.
