Tried searching for it now as I was curious too, can't find it either.
Except that this is in an Arsenal forum. Thus you would expect most arsenal fans to have watched the match, and seen with their own eyes the impact of the ref on that game. They were better than us, but the ref certainly influenced the result.
It doesn't matter what "people" stop believing.
You would expect most Arsenal fans to, you know, support the team rather than sniping at them at every opportunity and acting like they just can't wait for them to fail so they can moan about us not winning a trophy they thought we had no chance of winning anyway. Meh.
Well no, people have a life outside football, I watch football but sometimes I have other things that need doing, I'm not a kid with nothing better to do that sit and watch telly all day long.
My observation is one of how people blame the ref every week, I've watched plenty of games and where the ref didn't do a whole lot wrong but is once again blamed for this and that.
