If he isn't going to give 100% unless the fans suck up to him the he can get fucked. He should be thinking of how the get the fans back onside, not the other way around.
I remember the pre-season Nasri was set to leave he was getting shit loads of abuse, which I'm not advocating personally but it is what it is. He subsequently put in one of the most committed performances I've ever seen from him just before he left that actually won some fans over who were chanting his name by the end. That's how it should be.
The inferiority complex among Arsenal fans these days is amazing. Celebrate the wankers who piss on the club and give shit loads of abuse to the ones who are here.
