Callum Hudson-Odoi is set to stay with Chelsea with Bayern Munich now finalising a deal for Douglas Costa.
Costa, 30, who left Bayern for Juventus in 2018, will return to Bavaria on loan, according to Sky Sport Germany.
Bayern boss Hansi Flick hailed Hudson-Odoi as 'one of the biggest talents'.
Hudson-Odoi was targeted by the German champs last summer but a move failed to materialise before he penned a bumper long-term deal in West London.
The Blues academy product made his first start of the Premier League season in the 4-0 thumping of Crystal Palace on Saturday.
But he faces competition from new signings Hakim Ziyech, Timo Werner and Kai Havertz as well as American ace Christian Pulisic with game time potentially tough to come by.
