I personally do not believe the new Chelsea coach will quickly recover Chelsea's performance, because as far as I know and the surprise is about Tuchel himself as we know he did it quickly. Even when the Mourinho era came back at that time Mourinho was basically not a new person at Chelsea, but Mourinho failed to make Chelsea's performance improve. Therefore, it doesn't seem like all as lucky a coach as Tuchel made it fast for Chelsea upon his arrival. Now, at least there are names that are candidates to be appointed as Chelsea coaches like Zidane is also included but somehow I'm still not sure Zidane will accept it.
It's a shame when thomas tuchel had to be sacked with a decision that I thought was rushed.
like it or not, I think whoever will train Chelsea must quickly restore Chelsea's performance. but that doesn't mean I don't agree with you, we agree, it looks like Chelsea will not quickly recover their performance even though they change to a new coach. as for some names that will replace thomas tuchel, personally i like zanedine zidan. when he was a player or after being coach of real madrid, but as you said the question now is, is zidan willing to be coach of chelsea.
After becoming European champions, Chelsea's appearance continued to sag. The culmination of the last few matches: the team is difficult to score goals and easy to concede goals even though they have bought defenders with a well-known name. What else can be expected from Tuchel?
I think Thomas Tuchel should be sacked and now is the best time. The Premier League has just started, the transfer window has closed. The season is still long, and the new coach has had enough time to overhaul Chelsea's tactics and make the most of the existing players. The dream of becoming a benchmark Premier League club like Liverpool and Manchester City can still be achieved.
