UTD have been incredibly lucky. It's just a coincidence that we haven't. Focusing on their luck makes us feel worse. I believe we were getting the short end of the stick, but I also believe we spent much of the first half of the season causing our own problems.
The big disciplinary initiative this season was the crackdown on dissent. I noticed a change in attitude from the word go.
Except.... when we were playing. It was....oooh.... about a week, before we started being petulant, arrogant, dismissive - at times even aggressive - in the way we spoke to them. Pep's comments weren't helping.
Refs are emotional creatures like the rest of us. They see things 'getting better' for them, then see us very publicly disrespecting their colleagues on the pitch. What emotions do you think we inspired?
I think we got people's backs up. Then all but demanded the league has to make allowances for our style of football.
When Wenger said something not entirely dissimilar a few years back, he did so in reference to very visible incidents resulting in serious injuries. It created a debate about the protection offered to small, agile players.
This year, we've done it because we've lost points, or come close to losing them. And all the while, OUR discipline was really poor. We were more likely to be recklessly/aggressively causing injury, than suffering it.
(It won't have helped that someone like Ota is an obvious case of a con artist who only gets away with it because his attempts to influence the ref are so... weak ...nobody pays any attention.)
