Inter Milan have reportedly told Chelsea and Barcelona that Yann Karamoh is not for sale.
Both clubs have been linked with moves for the youngster in recent days.
The 19-year-old has impressed at San Siro following his summer move from Caen on a two-year loan deal.
According to Corriere dello Sport, Inter have responded to interest from Chelsea and Barcelona by telling them to back off.
Karamoh, who was reportedly scouted by the two suitors in January, is expected to be snapped up by Inter when the loan comes to an end as the Serie A club have an option to buy.
