After Mason Mount completed his £60m move from Chelsea to Manchester United, he became the seventh senior star to depart Stamford Bridge this summer.
Kalidou Koulibaly, Edouard Mendy and N'Golo Kante have all swapped the Premier League for Saudi Arabia, while Ruben Loftus-Cheek has joined up with fellow Chelsea academy graduate Fikayo Tomori at AC Milan. Mateo Kovacic and Kai Havertz, meanwhile, have completed switches to Manchester City and Arsenal respectively.
However, the exits have not stopped with Mount, with club captain Cesar Azpilicueta also leaving Chelsea to join Atletico Madrid. Azpilicueta spent 11 years with the club, having joined from Marseille in 2012, and helped them win seven major honours including two Premier League titles and the Champions League.
