The 18-year-old winger has already turned out for France’s Under-21 side after finding the net five times in Ligue 1 last season
West Ham and RB Leipzig are set to fight over the signature of Caen teenager Yann Karamoh, Goal understands.
The Premier League side and the Bundesliga outfit, who have regularly plundered France for its top young stars, are prepared to pay a fee in the region of €10 million for the 18-year-old attacker.
Monaco were previously in the running, but since signing Jordi Mboula from Barcelona have cooled their interest.
It is anticipated that Karamoh’s departure from the Normandy club will be formalised in the days to come, with Saint-Etienne having been put off by the high asking price for the speedy winger, who scored five times in 35 matches as Caen avoided the drop thanks to a 1-1 draw against Paris Saint-Germain on the final day of the season.
The Stade Michel-d’Ornano outfit are still trying to drive the price of the Ivory Coast-born France Under-21 international upwards, yet any deal should be completed imminently.
