Kelly's desire for senior football could be aided by a versatility which was illustrated on loan at Huddersfield Town last term.
"At the moment I don't know which is my best position," the 19-year-old told liverpoolfc.tv. "I'll play anywhere across the back four. When I went to Huddersfield I played at left-back for the first three games and it didn't seem any different to right-back. I don't mind where I play.
"I've been working hard on the tactical side of my game, which helps. That's coming along and I can't thank the coaching staff enough for what they've done to bring me on as a player.
"The defenders here are top-class players but I'll be trying my hardest in training.
"Training with them every day is fantastic - I can't wait to get out there with them and then I don't want the training sessions to finish."
