I agree with you. I think Pochettino has given his best this season. His performance deserves appreciation and is still worthy of being retained as a coach. Chelsea is building their squad. I think it will take years and have to be consistent. Like what City did by building a squad for years until they finally managed to get the treble winner. Enzo Maresca is a good coach. I can't wait to see his performance in pre-season.
It's not easy to handle a big team like Chelsea, pressure always comes from all angles when the club's performance is unstable. Pochettino almost found the right formula to improve Chelsea's performance, but the increase in performance that Chelsea experienced as the season drew to a close meant that Pochettino failed to make his team finish in a better position.
Chelsea management took the decision to dismiss Pochettino too early, if he was given the opportunity for at least one more season, perhaps Chelsea could provide competition in the title race. Now that a new coach has arrived, they have to start from zero again to build their squad. Usually coaches will have difficulty determining a suitable strategy in several official matches, Enzo Maresca has to repay the trust given by Chelsea management to improve the club's performance.
