The 21-year-old joined Chelsea from Basel for €14m last summer, signing a contract until 2031 and spending four months on loan at Juventus.

The experienced winger, who’s shown distinct signs of decline since swapping Manchester City for Chelsea, struggled to garner the faith of Mikel Arteta, and he ended up scoring just once in 28 appearances for the Gunners.
