I also think so, this is Chelsea management's fault, they shouldn't have fired Pochettino after Pochettino managed to show much better progress since he became Chelsea coach, everything needs a process and Pochettino has done it well, but the steps taken by Chelsea management are quite surprising, I think this is again the same mistake as last season made by Chelsea management.
Now Chelsea is recruiting Enzo Maresca. It must be admitted that Enzo Maresca is a good coach, but I'm sure it won't be easy for Enzo Maresca to immediately improve Chelsea's performance, everything needs a process and time.
Maybe Chelsea management wants to get very good results in the near future or in the near term, which is essentially Chelsea management wants instant results with Chelsea management firing Pochettino. Maybe Chelsea management is not satisfied with what Pochettino has done for Chelsea. Even though it is true that Pochettino has succeeded in showing progress that is at least better than before, perhaps it is because Chelsea management is impatient that he has taken action quickly which is quite surprising.
That's true, even though Chelsea have recruited a new coach, if they can't accept the process time, maybe the same thing will happen again, unless they can be patient in the process, maybe good results will be seen, I hope Chelsea can perform better in the competition next season.
