Calum Hudson-Odoy submitted a transfer request to Chelsea with a bid of Bayern 35 million pounds, sources said.
18-year-old Hudson-Odoy was the subject of four Bayern Munich offers but Chelsea did not want to release his young star and offered him a new contract that is estimated to be around £ 85,000 a week.
But despite the offer, Hudson-Odoy continues to seek to leave Chelsea and head to the Bundesliga, with sources claiming Bayern's bid is the only one on the table, despite Leipzig and Liverpool's interest.
Hudson-Odoy was expected to start for Chelsea in the FA Cup Cup Fourth Round against Sheffield Wednesday in Stamford Bridge, but this latest development may complicate his participation in the match.
Chelsea faces a public charm in an attempt to change Hudson-Odoy's opinion as Bayern's interest in him has become famous after chief coach Maurizio Sari praised the improvement of teenagers in training in recent weeks.
The public prosecution of Haussmann-Odoy from Bayern also angered Chelsea, and earlier this month sources told ESPN FC that the Blues are ready to report the German giants to FIFA if evidence of an illegal approach to the player or his camp is found.
Chelsea declined to comment when he contacted ESPN FC.
