The Under-19 France international striker came in on loan from Paris Saint-Germain in the summer as Rodgers decided to bring in a third striking option.
It could take a whooping fee of around £7m to make his move permanent with Celtic with Rodgers waiting on a number of factors before deciding whether he should try and keep him in Scotland.
“I will assess it at the end of the season,” the Celtic boss told the Daily Record. “He has grown each week he has been with us. There’s no rush.
“It’s for both sides as well. He might love it with us, he might not. I know he is really enjoying it but there is no rush to commit on either side now.
“It’s just a case of seeing how it goes in the second half of the season and we’ll review it then.”
Rodgers added: “He is getting better and better each week. The boy has big talent and is a real worker as well. He’s the type of performer I like.
“His English is getting better through lessons and he’s still only very young at 19 so he has a lot of potential. I don’t have any qualms if I have to put him into a game.”
