Past the anger phase now, it's more just disappointment that we can have such shit officiating.
For me, this is a prime example of why the referee and VAR official should me mic'd up (as in Rugby, Cricket etc). There is simply no way that goal is given if Atwell speaks to VAR and says "we've got offside on the pitch as it looks as though Rashford is interfering with play. Is he?"
I know (or at least think) they didn't bother with VAR on this one, but if you're getting audible validation or contradiction that all the fans can hear, it would take the subjectivity out of it.
Actually, I am still angry.
