Bayern Munich have reportedly submitted a formal bid to Rennes for Chelsea-linked Desire Doue.
Transfer expert Fabrizio Romano has claimed that Paris Saint-Germain are also expected to bid for the Frenchman.
Le Parisien has previously reported that Bayern recently had a £30million bid rejected by Rennes, leaving a good indication about the minimum amount the Blues would have to cough up should they want to win the race for the star themselves.
The winger is spending this summer with the France Olympic football squad.
