He offered some encouragement with the former England man on his way back to Liverpool for the start of the new term.
"I met up with Joe Cole when I was in Spain - I certainly know he's looking to come back," said Rodgers.
"Joe is a very talented player. He's obviously gone out to Lille and done very well. He has the opportunity to come back here and show his qualities.
"For me, it's fresh for everyone. Of course, I know lots of the players and their qualities, but Joe is obviously a player who'll want to come back and show his worth to the group."
