Carragher, who retired at the end of last season, reckons his former club can keep the 26-year-old at Anfield next season.
He told The Sun: "I think he might stay. Some big clubs will be interested in him because he is such a top player and that is something we have to accept.
"We can't complain about that, we bought him off Ajax. He signed a contract last summer and he has a few years left and hopefully we can keep him.
"He is very important. He was probably the best player in the Premier League last season and you want to be keeping your best players, which is what he is."
