Chelsea have rejected an offer from Bayern Munich for Callum Hudson-Odoi.
Bayern offered just under £20m for the 18-year-old forward, who has attracted interest from several clubs.
Hudson-Odoi, whose contract expires in 2020, has impressed when given a chance in the Blues first team.
But his contract situation and the fact he has barely featured under Maurizio Sarri have alerted clubs to his potential availability.
Hudson-Odoi’s appearance as a substitute at Watford on Boxing Day is his only Premier League outing since Sarri took over as Chelsea boss during the summer.
