Sincerely I also think so that bringing in Graham Potter was not such a good idea after all. They would have been more patient with Thomas Tuchel and supported him to get the team back on track but they opted to go for Potter who showed promising signs at the beginning of his take over and slowly declined and the team are back to losing games again. We shall see how things turn out when the league resumes.
Currently team having by Graham Potter with Brighton Albion I don't sure he can success with Chelsea without any experienced yet with big top team and not get trophy in his career. What have been worry is coming true right now with Chelsea can't win in last five matches and have beaten last three matches in a row at Primer League. I think Chelsea management have give huge pressure for Graham Potter if want long term existing at Chelsea actually Champion League trophy become realistic chance.
Its looks domestic league bit difficult reach to top standing after remaining many points with Arsenal, but Chelsea still have opportunity to win Champion League and learned more what the best achievement from current Chelsea manager Tuchel success in the first season with Chelsea become the winner in Champion League.
