Yes we did get our money back for Morata, but he was absolutely useless. We replaced Costa with Morata, which was a clear downgrade for a lot of money and was a huge influenc in our extremely decreased number of goals in the 17/18 season.
Ampadu: another useless player, didnt strenghten the team at all
Rüdiger was absolute shambles before Tuchel came. Remember that 99% of Chelseas fanbase wanted him being sold to Spurs before his Tuchel revival. His reception today is heavily influenced by his Tuchel performance, before that we was basically seen like Cucurella today
Emerson was a backup, yes, but to who?? Fucking Alonso. And yes, Alonso scored a few goals but everyone knew how limited he was and that we kept him way too long. So instead of buying a LB that is actually better than Alonso we chose to just buy a mediocre backup. Not making the team any better
Barkley: another player that didnt give the team anything
Drinkwater Bakayoko as well
Only Giroud was a useful player.
We were champion in 2017, but the problems in the squad were visible, we heavily relied on Hazard. But we had a good foundation to become a dominant force in English football. But instead of actually strengthening the squad with quality buys, Marina and Emenalo in their hybris chose to just add backups and additions to the team.
Only 1 player was actually useful and it was no surprise that we didnt get into top 4 in this year.
It may have not been a financial disaster, but this transfer window was a turning point in Chelseas history. After this window we werent able to challenge for the title anymore.
