Chelsea changed a lot after the British government forced Roman Arkadyevich Abramovich out of Chelsea as owner. Then Todd Boehly took over the club as the new owner which in the end made many changes on the management side. Todd Boehly was desperate to bring instant glory to Chelsea in his first season but the truth is that everything he's done this season hasn't turned out well.
I'm not entirely surprised how Chelsea have been this season because they are essentially in transition. It takes several seasons to build a good team and collaboration both internally and externally, and this will be achieved by Chelsea in the following seasons.
It does take time to build a team when you are bringing in new players into the club. Todd Boehly cant take ownership of Chelsea from Abramovich and expect things to be going in his favor in the first season after sacking Tuchel and bringing new coaches and players into the Chelsea team. No team has ever remained formidable when there are so many changes made in the team in terms of players and coach. I'm not entirely surprised how Chelsea have been this season because they are essentially in transition. It takes several seasons to build a good team and collaboration both internally and externally, and this will be achieved by Chelsea in the following seasons.
From the picture above, 90% of Chelsea players are gone out of Chelsea. Remaining 10%. The 10% would soon leave Chelsea.
It's unfortunate that Chelsea had a bad season last season, I am looking forward to it being corrected by the upcoming season by Pochettino and his new signings(players)
