I want to ask, what do you think. which new coach is suitable for Chelsea, who was able to bring Cheslea to win the Premier League trophy as well as the Champions League in his first season as a coach, with the players available, plus several injuries, and others underperformed.
I think the answer is simple for this. The right manager for Chelsea has always been Thomas Tuchel. Just because of not meeting some criteria of the board Tuchel was sacked. It wasn't for only the bad start to the season in fact. You can't expect any manager to be too consistent every time in the end. Tuchel achieved great successes with Chelsea as you said. He had a bad start in this one maybe but he could have made things right for the team if he was given a little more time. The fans must also be unhappy about this change now.
Tuchel's situation was similar to Klopp. Klopp is also facing bad times with Liverpool in the league this season despite playing solidly in the Champions League. But Liverpool board must be trusting him fully for the sake of his great achievements with the team so far.
My question is a coach other than Thomas Tuchel, who deserves to replace Potter. and you have answered yourself, that Chelsea's current situation and condition is unfavorable with the underperforming performance of its players, plus injured players and that's why Chelsea's performance declined which in the end Tuchel was fired regardless of the club's internal polemic behind it.
like you said, we can't expect any manager to be consistent all the time. even Tuchel himself had a bad season, and you say Tuchel can improve things and it takes time to fix it. So, especially for a new coach. at least, Potter also needs time to be able to recover the performance of his new troop, he needs chemistry with his players, he also needs some experimentation with the available players. so don't expect Chelsea to instantly perform great again with injured players and others underperforming. at least, let's give him time and appreciate the effort to rebuild Chelsea.
even if Potter failed to lead Chelsea to a top four finish, he would be sacked. for Tuchel, he is the past of Chelsea. maybe in the next season, he will coach a new club. in Jurrgen Klopp's case, if he is unable to lead Liverpool to a top-four Premier League finish. it is likely that his career will end, unless Klopp is able to bring the Champions League Trophy to Anfield, Liverpool headquarters.
