I think Chelsea has started picking form, and understanding their coach Graham Potter, is clear that the players and new owners where getting tired of Tuchel and potter coming gives them this new energy, for me before Tuchel left he has assembled a very strong squad, team filled with world class players before he left, take a look at Chelsea defence, koulibaily and thiago Silva are world class, they got recce James and cucurela at wing backs and sterling and Aubameyang at attack.
So far, the transition of Chelsea game scheme from Tuchel to Graham Potter has been increasingly successful by Graham Potter in several matches where Chelsea players have been able to adapt to the tactical scheme of Graham Potter. in fact because in 5 the match chelsea were able to get 4 wins and 1 draw which made their position even better in the domestic league and in the champions league. Chelsea management brought in Graham Potter at the right time because graham could immediately give victory and victory.
