Chelsea's like a revolving door for coaches. In, out, in again, out. Ridiculous. Does it improve the team? Absolutely not! Its a mess. Its chaos. Building a winning team is not done that way. This Enzo man has some respectable experience, now. He has been with winners like Pep. He returned Leicester to the major divisions. That is excellent and rather remarkable. Yet Chelsea? It is a cooker under pressure. Can he manage that? We'll see.
It's going to be tough to handle Chelsea who you liken to a pressure cooker because the team themselves always want good results quickly without wanting to see the process first. Chelsea should realise that in order to make a team better it has to go through a process that doesn't even take a short time to achieve what they want. Because in the Premier League the competition is very competitive and I think Chelsea already know that so they should realise that changing managers every season is not going to change anything in their own team.
I agree that any coach who's managing Chelsea right now needs time before he can perform better. It's not easy to achieve success with new players who do not understand each other's style of play very well and a struggling club. Chelsea management always provides funds for any new coach managing Chelsea to buy any player of his choice. But if the coach fails to win silverware or qualify Chelsea for the UEFA Champions League competition, he will be sacked because he was provided with the players he wanted, and yet he couldn't make Chelsea play competitively.
