Chelsea have rejected a bid from West Ham for Conor Gallagher.
The midfielder might well leave Stamford Bridge this summer but Chelsea have turned down an offer of around £40m from the Hammers.
Gallagher, 23, has two years remaining on his contract.
Having impressed while on loan at Crystal Palace – and made his England debut – he returned to Chelsea last season and made 45 first-team appearances.
Several other clubs have shown an interest in Gallagher, who is expected to attract more bids before the transfer window closes.
