Chelsea have changed several coaches and have brought in many new players in the last 2 seasons but there has been no significant improvement in their performance, I don't understand where their weaknesses are even though they already have everything the club needs. Maybe they should stand with one coach and build unity for the long term like what Manchester City or Arsenal have done. of course, it is not easy to change a system or strategy every season because players will need to make adjustments again.
Now it is clear that replacing a coach too often on a team does not guarantee good performance for that team. And this has been felt by Chelsea so it is very sad for Chelsea who have spent a lot of money, but the team's performance is still beyond expectations or expectations. I think Chelsea's management also needs to be improved in order to find out where Chelsea's weaknesses are because with a new coach and new players it is still not enough to bring about better changes for Chelsea.
Even though Chelsea often fires coaches in the middle of the road, Chelsea has managed to become UCL champions twice when they fired coaches in the middle of the road, in the 2011-2012 season Chelsea managed to become UCL champions after firing Andre Villas Boas in the middle of the season then replacing him with Roberto di Matteo, and in the 2020-2021 season Chelsea managed to become UCL champions after firing Frank Lampard in the middle of the season then replacing him with Thomas Tuchel.
In my opinion, sometimes changing coaches can bring improvements so it doesn't always have a bad impact on the team. However, in Chelsea's case, there are currently many changes, starting with the club owner and many players changing. So giving Mauricio Pochettino the opportunity to build a team really takes a long time, it is very natural that Chelsea has not been able to recover from its current downturn. Chelsea must believe in the process, because there is nothing instant in building a new force.
