Yes, very mature esp after such a defeat and we all know that most managers are potentially only 3-4 defeats away from the sack so this stuff does matter.
Personally I think football was better before VAR, but after we had goalline technology, which is pretty obvious and clearcut. I know it's difficult, but I do wonder if it is taking too much away really. At the very least I think we need a far more sensible interpretation of onside where being level means you are onside. It only exists to stop goalhanging, it doesn't matter if a striker is a mm or two Infront.
