The French youth international could make the switch to either the Premier League or the Bundesliga.
The youngster's current club, Caen, seems resigned to losing one of their best and brightest sooner rather than later.
This season, Karamoh made 35 appearances for Caen, starting 25 games. He scored 5 goals and laid on 2 more.
At the moment everything seems to suggest that he will leave Caen this summer, the only question that remians is where he will go.
Both West Ham, who disappointed last season, and Leipzig, who came second in the Bundesliga, are hoping to convince the youngester that his future lies with them.
