Yeah but it was never a red card so it's hardly his fault.
In life, what's your fault and what you are blamed for, are two different things. I don't think any fans will be too angry given they got the points. But negative incidents will always have an effect, even if only subtle.
I think it was clumsy enough that while Hull were on his side and angry at officials, he wasn't totally forgiven for giving them the chance. If they'd stayed up, he would be one of the heroes, they didn't so he's one of the many turds.
Michy Batshuayi didn't win Chelsea the league, but that one touch and goal changes everything for him.
