We select six important tasks facing the new manager, also including getting Mason Mount back to his best

Transmit his playing ethos

Graham Potter has built a solid management reputation by assembling teams that play according to a defined style of play. Chelsea has the players to adopt his passing style, but it remains to be seen how quickly the former midfielder for Birmingham and Stoke will spread his ideas. 

Although Potter faces an uphill battle to emulate Tuchel's achievement of winning the Champions League, he will have no illusions about the expectations of his new employers. Tuchel is renowned for getting things done quickly after taking over from Frank Lampard at the beginning of last year.

Organize the defense

The solid three-man defense at Stamford Bridge was the foundation of Tuchel's success during his first few months there, but the departures of Antonio Rüdiger and – to a lesser extent – Andreas Christensen created a massive issue.

 The signings of Kalidou Koulibaly and Wesley Fofana for a combined £103m should resolve those issues once both have properly found their feet but, for now, it is likely that the new manager will have to lean heavily on the 37-year-old Thiago Silva. Keeping both costly left-backs, Ben Chilwell (£45m) and the former Brighton defender Marc Cucurella (£55m), happy will also be a challenge, although you can bet Potter has a plan..
