Hopefully Todd Boehly will not regret his decision to stop Mauricio Pochettino as one of Chelsea's best coaches. I don't know for sure how Chelsea will be next season. Does Chelsea have a new coach who can improve Chelsea's performance and provide victory next season? If Chelsea always does this then the possibility of Chelsea winning will be very difficult to obtain.
If every season Chelsea always replaces their old coach with a new coach, of course Chelsea will always find it difficult to find more wins in every new season they live. Because every new coach is different in the way they train players and also different in how they read the players' character, so changing coaches in each season will actually have a big influence on the good and bad of the team's performance. Although dominantly it might be worse if the coach was not experienced enough in coaching an English team like Chelsea.
