The Englishman is at Borussia Dortmund, where he has lit it up for the past season and a half.
He is likely to be the subject of big money interest from several Premier League clubs.
And Carragher, a Sky Sports pundit, believes the former Manchester City youth star would be a hit in the Premier League
"He's an English player who I think will be desperate to come back, so I think he'll be the hottest thing everyone in the Premier League will be looking to bring in.
"Will he be a hit? I think so. It's a no-brainer, look at how well he has played in a top league with a top club under pressure. He's playing week in, week out, his numbers are fantastic and his age is just perfect."
