Chelsea had a truly miserable Saturday. Not only did they get beaten by title rivals Manchester City, but it was their former player, Kevin de Bruyne, that scored the decisive goal with an absolute screamer from 20 yards.
To add insult to injury, star striker Alvaro Morata was also forced off with a hamstring problem in the 35th minute.
Despite being at the club for just a few months, the former Real Madrid man has been sensational for the Blues this term, having already scored seven goals for his side in all competitions.
Although the severity of the injury has not yet been confirmed, questions marks remain whether he will be fit for Chelsea's next game on October 14 away at Crystal Palace.
If he is set for a lengthy lay off, Chelsea will struggle to provide the same attacking impetus in his absence.
Although Manchester City dominated for large periods of the game and many Chelsea players struggled to cope with their quality, one man in particular has come under fire from fans.
In fact, it was Morata's replacement, Willian, that received heavy criticism on Twitter.
After being introduced in the 35th minute, the Brazilian struggled to cope with the pace of the game as he gifted possession to the away side on numerous occasions.
A video has even emerged emphasising just how much of a shocker the Chelsea winger had.
Accompanied with hilarious music, you can watch the brilliant video here:
Antonio Conte has also come under criticism for choosing to replace Morata with a winger; especially with back-up striker Michy Batshuayi also on the bench.
After Morata departed, Chelsea struggled to create any real goal-scoring opportunities and in truth Ederson had very little to do in the away goal.
When looking back in hindsight, the Chelsea boss will probably be admitting to himself that replacing Morata with Willian instead of Batshuayi was the wrong call.
They eventually lost the game 1-0, and now slip to 4th in the table, six points behind joint leaders, Manchester City and Manchester United.
Although it is still very early on in the season, the two Manchester clubs look a class apart at the moment and the chasing pack will need to improve drastically if they are to prevent the Premier League becoming a two-horse race.
