Nah, Squillaci loves you lot forever and will stay until he's 40, becoming a club legend.
That's partially because Arsenal just don't grind out wins. Ever. They either destroy the opposition 5-0, get 3-0 up and then cruise home to a comfortable victory, or they go 1-0 up, start retaining possession, and the opposition rips them apart on the counter or just batters through on sheer physicality. Those are pretty much the only three types of Arsenal game. Another cliche, but for what is a relatively big (physically) team now, Arsenal really need someone who actually puts up a fight and isn't Jack Wilshere.
It brings back that old chant "1-0 to the Arsenal", they could do with that. Now I love it when my side plays brilliant football on the way to winning and that should always be the aim for a side like Arsenal, but sometimes you just have to brawl and scrap your way to a win. Unless you're Barcelona, then always be Barcelona.
