Yes Chelsea are still reliant on Graham Potter for his service next season, thru do not have a problem with him and are still backing him for long term plans for Chelsea, Chelsea expecting a quick results not knowing Graham Potter will have to adapt to the squad with some losses. Chelsea will pull up back stronger and help them selves fight for top four which is looking impossible
Of course nothing is impossible about that, Potter has a great job for Chelsea and he has to prove it.
Potter may still need financial support to spend on the upcoming transfer window to really have his strategy work out in his favor. But I doubt if Chelsea will really agree with that, but definitely the addition of some top players will help Chelsea get out of the problems that are not satisfying at the moment.
The main problem for Chelsea right now in my opinion is, that they don't have a striker who is capable of scoring many goals in matches. Aubameyang hasn't looked good enough at Chelsea, and the decline in the form of other strikers has made Chelsea suffer. 17 goals per 14 games, Chelsea are only slightly better than Crystal Palace and Aston Villa on this statistic.
