Chelsea are currently not doing well because the strategy they are using has failed to lead them to victory. It can be seen that in their last game they did not manage to get a win. If Chelsea already have competent players and a good strategy, then it will be easy for them to win, so what needs to be corrected is the strategy they use, and teamwork must also be considered.
It could be that Chelsea's mistake lies in the strategy or the way they face their opponents, but in the second match of the season Chelsea faced a team that is not weak so that factor must also be seen in the defeat that Chelsea got in their second match of the season. In addition, Chelsea's young players must also be trained to be better by the Chelsea coach so that they can become a good mainstay for the Chelsea team this season.
If I'm not mistaken, Chelsea is the only team in the Premier League that has purchased more players this season, and yet nothing has changed with their performance. To be honest, Chelsea needs to train their young players very carefully because it seems like all of these players don't take it seriously when they are playing on the pitch. I believe that Chelsea is doing something that makes the team's performance appear to be very subpar. After all, the team regularly purchases players whose abilities and intelligence are well known, but whenever Chelsea adds a new player, his performance will undoubtedly suffer if he agrees to join the club.
My mind is still telling me that the reason why Chelsea players occasionally behave in that manner is because Chelsea used to purchase the player with a significant offer, which gives them the impression that they are perfect and can do whatever they please, Chelsea should just be Chelsea. However, in my opinion, I don't believe that all of the issues are the team coach's fault because the formation the coach use for the team that day is good, and many teams are using it to defeat their opponents.
