If he was Sunderland manager I'd admit he took us down and achieved the bare minimum of promotion after assembling a squad costing 50 60 MAye and I suppose if he was Sunderland's manager you'd be berating him, saying he's failed everywhere he's been, chequebook manager etc.
Doesn't make you less of a sunderland fan if you manage to look at a situation objectively involving Newcastle you know, it's OK to say he's a decent manager and you wouldn't mind somebody like that at Sunderland.
