Fikayo Tomori doesn't like playing against Chelsea. His record against the club that helped to develop him is without triumph and each game has been marked by a disappointing mistake to mar the match.
Before he had made an appearance for the first team he scored an own goal against Chelsea for Derby County at Stamford Bridge. Four years later and his next two matches against the Blues resulted in a 5-0 aggregate loss in a reunion that was supposed to prove why Chelsea had made a massive error in selling him.
Ultimately, Tomori's mistakes don't detract from the poor business that getting only £25m for him last summer was, but his performances didn't create the ironic backdrop to Chelsea Vs AC Milan that it could have. Whilst Kalidou Koulibaly returned to form and Thiago Silva continued to grace football with his defensive glory, Tomori was exposed and struggled to assert himself.
