Chelsea manager Thomas Tuchel has reportedly identified 10 players he is willing to part ways with in the current transfer window.
Despite spending big last summer and marching to their second Champions League title, the Blues are thought to be preparing significant improvements for their squad ahead of the new season.
The Blues are understood to be in discussions with Sevilla over a deal for Jules Kounde and have also been tipped to bring Romelu Lukaku back to the club, with a deal for Erling Braut Haaland looking increasingly unlikely.
Chelsea's defence could be heavily depleted after Tuchel's summer overhaul, as The Mirror claims that Kepa Arrizabalaga, Kurt Zouma, Marcos Alonso, Emerson Palmieri and Davide Zappacosta are all on the chopping block.
The report adds that Michy Batshuayi and West Ham United-linked Tammy Abraham could also be on the move, as well as fringe midfield trio Ross Barkley, Danny Drinkwater and Tiemoue Bakayoko.
Most of the 10 players listed featured during Chelsea's 2-1 pre-season win over Arsenal at the weekend, and the Blues' final exhibition match in the Mind Series sees them take on Tottenham Hotspur on Wednesday.
