I'd love him to get the England job, there's no way he'd succeed and end up looking a numpty, he couldn't manage against us (atleast for a while) or nick our better players, he'd probably call some of our boys up and I can't stand the England national side (Villa aside) so if it did all go wrong it'd be a double whammy.
I'd hope his reception would be similar to the one Daphne and Celeste received when they played the Reading Festival. Non stop boos and bottles full of beery piss flying in his direction.
I think booing ex-players is childish and only spurs them on to play better, so I see no difference in doing that to an ex-manager either.
