Offers have been lodged for Chelsea striker Bertrand Traore.
Everton and West Ham are among clubs to have made bids for Traore.
“Bertrand is high in demand and offers are coming in," a source close to the forward told Foot Mercato.
"Everton, West Ham, Borussia Monchengladbach, Lille, Lyon and Schalke have made concrete proposals to Chelsea.
"One of these clubs has even offered €17m [£15m].
"The club wants the best possible deal for Bertrand and do not want to negotiate for anything less than €20m [£17.5m]."
