The Belgian frontman will undertake a new challenge in the Turkish Super Lig after being deemed surplus to requirements at Stamford Bridge once again
Chelsea striker Michy Batshuayi has joined Besiktas on a season-long loan.
Batshuayi will spend the 2021-22 campaign with the Turkish club after passing a medical at their training ground on Wednesday.
The Belgian extended his contract with Chelsea until 2023 before departing, but it has been reported Besiktas will have the option to buy the Belgian outright for between £5 million and £11m next summer.
