Mauricio Pochettino did not deserve to be sacked for many reasons. Firstly, Chelsea showed a positive trend in their results. The club was in 10th place after the first half of the season, but finished the season in 6th place. Secondly, under the Argentine coach, the players started to improve. Cole Palmer became the best young footballer of the championship of England. Nicholas Jackson started to add value. I think Pochettino did a good job at Chelsea and the club management should have extended his contract for one more season.
It's what it's.
I hope Chelsea will back become mediocre team like before managed by Pochettino, so Chelsea will realize if what they did is a big mistake. And the same time I also hope Pochettino will find a team that better than Chelsea.
The rumors that flowing around Bayern Munich and Manchester United are interested with Pochettino, but since Vincent Kompany already become Bayern Munich's coach and Manchester United looks like want to keep Ten Hag, I have no clue which team he would join.
