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.
I have always bought into this opinion since I learned pochettino has been sacked, I know it's been the tradition of Chelsea management to sack their coaches at will especially if within the shortest given time you are unable to deliver as they have expected of you, but with pochettino I saw really different and I can't even say for sure why exactly they will let go of him even without a very valid reason enough because I personally don't think there's any.
Chelsea started off poorly this season and it felt like they weren't going to have a decent finish but then pochettino was able to keep fin tuning their tactics and strategy till towards the end of the season when he was able to get series of wins which gave them a productive end and a very decent finish such that even Manchester united that was far ahead of the now had to run behind them and depend on winning the FA cup to be able to participate in another league game aside the premier league by next season but it was really different with Chelsea.
The board just seem not to have that patients enough to give coaches time enough to be able to see if they can get their teams soughted out before letting go, it's not workable with every coach, some Coach needs More than a season to be very productive enough meanwhile some other may be very good In their first season a d turn out terrible in the next just like that which is send in Manchester united.
