Why?
He's not a stupid man in terms of intelligence. So either he's had a mental breakdown (as I have suggested) or he's deliberately put his own interests over those of the club, something he said he would never do. I don't think you can feel sympathy for such a selfish individual. You can pity him, despise him, hold him in contempt, but have sympathy for a guy who must surely have known the risks and took them anyway so the needs of the one could take precedence over the needs of the many?
If he's had a breakdown then it's Kroenke that deserves our contempt for allowing a sick man to continue in this position and be battered from all sides. Well, Kroenke deserves our contempt anyway so nothing new there.
But I won't be joining in the Wenger love-in that will inevitably occur when he leaves. That bridge was burned the minute he signed the last contract. Blown up in fact given the way he bypassed his own (alleged) boss and ran to Stan. And how can you have sympathy for a man who is so arrogant he simply refuses to listen to the tidal wave of opinion that is pointing out the obvious?
Like any dictator, he craves power and he's done whatever it took to hold onto it. I don't respect that and I don't sympathise with it and no matter what the guy has done in the past he won't be forgiven for what he's done in the present - not by me anyway. Which I know will come as a severe blow to him because he respects me just as much as I respect him, in fact he "respects" all the fans in the same way. He's blamed us enough times for his failings after all.
