Pochettino not really failure for his first season become Chelsea manager, got problem with many senior players selling by management and he has home work how to make young players adapting well with his tactician on the first season. I think every manager need time developing their tactician actually Pochettino get leaving by many senior players and management give him most of young players get their first appearance for playing in domestic league.
I think Enzo Maresca will get more easily with tactician leaving by Pochettino because he can build good composition for next season after some players get adapting well on their first season with Chelsea.
I can agree with you. Pochettino actually could reshape again Chelsea squad well. He can lead Chelsea to finish in 6th place, it is not a really bad position. Unfortunately, the management of Chelsea doesn't care with the improvement, they still fired him at the end of the season. TBH, I'm surprised with the decision of Chelsea management. Moreover, the change Pochettino with Maresca. I personally think Pochettino is much better than Maresca if we consider their career so far.
In theory, Maresca may be easier to manage Chelsea. But since it is the first time that he manages Chelsea, I am not sure if it will be quite easy for him. Morever, if Chelsea players don't really trust him and may not suit with the tactics used by Maresca, it even may lead to a bad situation for Maresca. So let's see how Maresca can adapt with Chelsea players!
