Yes, the quality of squad available to the coach plays an important role on the outcome of the team in various leagues, if the team are quality enough probably at their own best they might achieve better results than a club with a better coach and less potential players. If peradventure the both managers are to swap teams then Pochettino will do better managing United than Ten Hag on Chelsea, it's my own observation without being biased I always feel this connection between Pochettino and his players. Chelsea really made an awful decision letting him go so easy, he would have done better in more season to come. Manchester United are keeping Ten Hag for another season, let's see how he does this time.
The owners of Chelsea are not having any patience, they want results because they have spend too much money on the club but they are not seeing their money being used very well to better Chelsea as a football club. Pochettino would not have taken Chelsea to the level the owners of Chelsea want to see Chelsea playing at. There is no time to give the coach that chance to build up the team slowly, they want a fast response and for Chelsea to be playing with the top clubs. The sacking of pochettino is not going to be a regret by the board because he is not the right man for the job in spite of how well Chelsea were playing at the end of the season but by then it was already late because he did not start strong when the fans and everybody were expecting him to use his experience to make the players play good football.
I doubt the patience had anything to do with it considering the fact that if the owner is always thinking about money. Chelsea had let Pochettino one more season to excel but he brough a few improvements but i think that's good enough. The owner of Chelsea is the primary issue since he now views his team as a means of generating income and this is why boehly is trying to push chelsea and coach to help him build the good performance. Todd can sell their players then. He totally differe with abra which was seeing owning the club as his hobby. It is not the issue of winning a prize as quickly as feasible. The club is concentrated on player development so that it may sell the players for a great profit.
Since Chelsea, this has been their primary issue. Todd had been putting up a lot of effort to make it happen. The most annoying part was that he was attracting so many players with average pricing of 100 million. This is the worst Chelsea choice ever.
Todd Boehly had to start from scratch again after he decided to replace pochettino. Chelsea was improving last season and is now on a good trend. I hope Maresca will be cooking something fresh for the club. Chelsea appointed him recently.
If maresca brings Chelsea down from its current position and im sure the owner might face criticism from many fans considering the worst decision from the owners. They had the owner so angry. Todd Boehly often revised his work in chelsea and this is really inappropriate thing for whole of blues fans. For Chelsea to become a successful team, this is just unacceptable.
I still have hope that if Maresca fails, they will take action for this like recruiting a good coach to manage the club. They will discover to stay away from hiring the trash coach again like this time.
