Kelly admits he's learned plenty from Carragher.
"He's been fantastic for the club and for me personally as a player," said Kelly to liverpoolfc.com. "Pretty much every time I have played he has been there alongside me. He has helped me through each game.
"I'll be really sad when he goes because there is so much more there for me to learn from Jamie. I'm sure he'll be around the club anyway, so he'll always be able to offer that experience.
"But he is a great player, a great person and I'll be very sad to see him retire."
