Pardew Sacked by Southampton - But for what exactly?

So Pards has been shown the door at Southampton but the big question is, why? It's not so many months ago that he won the lower division F.A. Cup and, but for the points deduction, Southampton would have comfortably finished in the play off zone last season. Southampton have won one, drawn one and lost one in the old Division Three and ran out 4-0 winners in their last game.

So why has Pards been shown the door? Up to his old tricks perhaps? You can't be a saint and a sinner it seems!
