The performance of Chelsea is still not getting better even after they hire a new coach and they are rebuilding whole the team. A few hours ago in the EFL Cup, Chelsea was playing against Wimbledon. While Wimbledon is not a strong team to make problems for a team like Chelsea with the investment they had, But the performance of Chelsea in this game was not good at all.
In fact when Chelsea got new owners they spent more than before but unfortunately the performance has not improved yet.
