The midfielder, who spent last season on loan at French club Lille, recently scored on his comeback from a hamstring injury for the Reds' Under-21 side against Fulham.
"His attitude is superb and Joe really thinks he can contribute to the group, which is great. He has been unfortunate," said Rodgers.
"He was out for eight weeks, trained for a couple of weeks, had his first game, scored a good goal and now he is fit. He is back into training now and looking to fight for a place in the squad.
"He loves his football, Joe, and he is now fit enough to fight for his position in the group."
Liverpool are next in action against Udinese in the Europa League on Thursday.
