I'm just not very comfortable with the assumed knowledge other clubs' fans seem to have of Arsenal. After so many years of 4th and not progressing, you can see exactly why people want a change. The fact Wenger has been a legendary manager shouldnt be used as a reason not to change; likewise I don't think the vast majority of anti-Wenger fans are being vindictive. I'm sure they know all too well what Wenger has done for them.
Pundits like Neville, while articulate in their point, are obviously going to get on the wick of passionate fans when he essentially says they should be happy with their lot.
