These names mentioned are still under consideration but I think Julian Nagelsmann is the bookmakers' favourite to replace Graham Potter. He is viewed as one of the most progressive young coaches in world football and has a number of admirers in England. But after seeing Chelsea sack two managers already this season, the club's level of expectation is set to be an important consideration for managers. Imo any replacement is welcome, but it will not change Chelsea's fate. Having an owner who puts fingers into everything and buys players like in a virtual game will stagnate progress.
I don't follow the premier League that closely but i think it was about time that Chelsea fired Potter because the team simply did not deliver at all and there was no progression to be seen at all. Regarding the potential next coach of Chelsea. I personally think, that it would be a way less risky move for Chelsea to sign Pottechino than to sign Nagelsmann. Pottechino has proven, that he can coach big clubs of the premier League and the spurs probably were at their peak during his years. Nagelsmann on the other hand did not really convince me as a coach of Bayern Munich. Bayern has a great squad this year but still Nagelsmann did not manage to make the team perform on a high level consistently.
