I agree, and you made some good points in your original assessment.
The problem is we only have two referees remotely good enough to referee the big games ,Oliver and Taylor.
City fans wont accept those two, but the others are hopeless , so currently for most posters it doesn't really matter who refs, the response will always be the same.
Personally I believe Taylor is the best.
Despite the "what about " reies.
I agree, Taylor is good in most games. I do think he leans towards United though, or against City. There have been a few instances that would support this view.
Some inexplicably favour certain teams though. One of the most bizarre performances was Mike Dean in United v Southampton, a few seasons ago.
United are leading 6-0 against 10-man Southampton, and there is a challenge in the Southampton area. United player goes down, penalty and red card!
I mean, if ever you give the benefit of the doubt to the losing side, it is here. It was before VAR, so not reviewed on the day. But the decision was soon overturned upon appeal.
United went on to score the penalty that wasn't even a foul, and racked up nine goals against nine-man Southampton. Totally unfair, borderline corrupt.
I think Dean had recently taken a review course on the updated Referees Handbook.
