Sacking Thomas Tuchel by the club and employing Graham Potter was for a reason and I believe if the reason for employing a new coach which I believe is to restore balance in the squad and drive the team to maintaining consistency and winning games so I wouldn't blame the fans if they begin to panic and ask questions or doubt Potter's capabilities because he was employed to improve the team and win games so if he is not doing so then it surely will raise doubts.
To restore balance in the squad and drive the team to maintaining consistency of winning games?, and Where are those facts since he was sacked ?, Whatever story that may have caused the sacking, I think that was a wrong decision by the owner and the entire Chelsea management board.
They Forgot that in live there ups and down times and same is applicable to coaching, I never sided the sack of Thomas Tuchel one day, that issues should have been resolved with the team or the management of Chelsea and with time everything would move back smoothly for the club entirely.
