Jol hopes to loan out the 19-year-old again this campaign to get regular first-team football.
He told the Fulham Chronicle: "Kerim is a young lad who's developing.
"He scored one goal in more than 25 matches, so he needs games.
"I would love to put him somewhere where he can play games and we can develop him, like we did with [Alex] Kacaniklic."
