I admire your stance here Ric, but no matter what the reasons are, that goal should stand, even if Sane was in an offside position, because under the current rules Sane is entitled to be there, and he made no attempt to go near the ball, and Mason knew that, which was why he originally gave the goal. He wanted a reason not to give it, to keep a big game for the TV broadcasters and sponsors open, so for me he went over to make it look like he'd taken advice. The replays show Sane is not offside anyway, so it should be a goal, and annoyingly one of our best goals of the season will never be counted.
As for the rest of Mason's performance, well you can view it however you want, but at the very best it was incompetent, and if not its something else, which most football fans don't want to believe happens, even though deep down we know it does, as Halsey and Clattenburg have both confirmed recently.
The good thing is now, 90% of the time they can try and stop us with decisions, but we're too good, so rather than let them spoil it for me, I'm going to take every win we get, when clearly there were efforts to stop us winning today as a bigger success, and I'll be sticking the 2 fingers up to it all, and continue to enjoy what we are doing.
When officials with certain known allegiances (Mason and Taylor in particular) are stopped from being involved in games that could involve the team they have an allegiance too, then I will know there is nothing sinister going on, until then I won't.
