Karamoh has just twelve months left to run on his current contract, and his club are prepared to sell the 19 year old for £9m this summer to prevent him from leaving for nothing next year.
Karamoh made his senior debut for Caen only last season in a 3-2 win over Lorient last August. Since then, he has made 36 appearances in all competitions, scoring five goals and providing four assists.
Last campaign he mostly played on a right hand side of a front three but his future is likely to be as a central striker. Back in June, he made his debut after coming on as a substitute for France Under 21s, playing up front in a 3-0 win over Albania.
