And the more important problem is that you need to find an outstanding coach who is willing to manage a team that does not play Champions League. That is a huge issue for Chelsea. I read that Nagelsmann was already there, but in Nagelsmann's case it makes more sense to wait and see if another Champions League club wants him. It could be Real Madrid, it could be Barcelona, the incentive to sign a contract with Chelsea right now is not that high unless the salary is unprecedented.
I don't think signing the coach will be an issue, the issue will be finding the coach. If we are been honest there are limited coaches out there that can really bring out the best of this Chelsea squad, They just have to take their time and analyze all their options well before they hire. They shouldn't make the mistake of going for a popular coach jut because he has proved himself in another club. The situation of that club is not the same with the situation of Chelsea.
Potter was superb at Brighton but he came to Chelsea and became ass.
Chelsea needs to be sure the coach they're hiring can bring out the potential of the players they have because most of the players they signed are young players with potential so if they are not managed properly they will not be able to harness that potential.
Currently Chelsea has a number of potential young players. Boehly seems to have a long-term project to rebuild Chelsea. But unfortunately he is not supported by a line of management who are able to manage the team well. In his first season as Chelsea owner, Todd had to see his team slump even though he had already spent a lot of money investing in the future of the club. I think Boehly should immediately re-evaluate the management side and then sign an experienced trainer. But if you don't fix the management side, I'm very sure Chelsea will be very difficult to return to compete for the top flight next season.
