Although I don't like Mauricio Pochettino very much, he was on the verge of great success at Chelsea last season. Pochettino is a system manager with a certain understanding of football. He has the potential to take his teams step by step to the next level. In fact, they had to be patient with him, but in today's world, success has to come instantly. However, Pochettino is a manager who can get good results with bad squads. I think Chelsea fans have no patience anymore and that's why if the Chelsea management fails, they blame it on the manager. If the Chelsea management is not patient, they will restructure the team with every failure. This means that Chelsea will fail for many years.
Indeed, the problem is patience, I am sure that everyone cannot be as patient as possible, but what is clear is that being able to produce the best certainly requires time in the process. Chelsea will not experience change if they continue like this. It is unlikely that I think Chelsea will find their best performance, even though they managed to recruit a coach who has long experience and good quality, of course to adapt they need a certain amount of time. but it's true what you said, the world today certainly wants immediate success, including Chelsea fans, who in my opinion don't want to know anything, they just want Chelsea to recover with good performance.
It's important to remember that finding the best and becoming the best is certainly not easy, and if Chelsea management is impatient then it's true that Chelsea will experience failure for years. I also doubt that any team can recover quickly, it seems almost impossible to happen.
