I will never forget what he did for Arsenal and we would have probably been a mid-table team without him. He made the new stadium possible and he made qualifying to the CL almost a god given right(which is new to Arsenal). So i will forever be grateful to him. But he's obviously lost the plot, he has been given too much freedom by the board, and he's been getting too little criticism from the fans. Basically he just isnt held accountable for any of his failures. I think it is best for all parties if he leaves. We will suffer for a year or two and possibly even not qualify for the CL once, but in the long run, it is best for all parties.
