That's not the issue because most if the fans chanting yesterday probably wouldn't say that to Wenger in a one on one. Most of the people abusing PHW, Gaz and Stan wouldn't dare say anything if thu had a one on one with them. It goes beyond the Internet. Mob mentality and strength in numbers.
But let's not pretend that we couldn't see this coming. Just watching Sunday Supplement and the pundits are quick to round on the fans in the first opening sentences but as they continue to discuss the problems they start to delve into the sort problems and frustrations that we've been having to deal with for years. Wenger knows there is only one way to silence disgruntled fans because he said it himself a couple of weeks back. The performance on match day is the only way to change things.
