The way Chelsea wants to restore team performance is not going to work for them, because it will be hard and challenging for a manager to restore a team that has been performing poorly for some seasons to get back in just one season and probably get a trophy, because that is what Chelsea management is looking for right now. They change managers.
Every season, and that is why they are performing, they always go back to poor performance anytime the season starts. Instead, they should have one manager for at least 3 or 4 seasons to see if he can deliver a good result, but Chelsea failed to do that. I believe there is no coach who will do that in just one season; rather, giving a coach enough time to see what he can bring to the table is the best thing.
Maybe Boehly wants Chelsea to have quick success like when Tuchel was Chelsea's head coach at that time with Chelsea sacking Lampard. Because after all, Tuchel really managed to achieve rapid success at that time by winning the Champions League trophy in the 2020/2021 season. Amazingly, at that moment Chelsea managed to beat Real Madrid in the semifinals and then Chelsea beat Manchester City in the final match. Obviously, it was a huge achievement for Tuchel at that time, because Real Madrid and Manchester City were the favorites to get the trophy.
But strangely, after this great achievement, Tuchel seemed to have lost his magic in making the team perform well, so that up to now Tuchel has still not succeeded in getting the team he coached to win a trophy. But about Chelsea continuing to change their coaches, I think they probably want quick success like that. But unfortunately, short success like that is very difficult to repeat because it also probably requires a high level of luck too.
Apart from that, many people think that the quick target of becoming champion will definitely be quite difficult because the competition that occurs in the Premier League is very intense and also in terms of strength the other teams are much stronger than Chelsea.
