Well Ashley made a blunder when he signed Pardiola up to a 8-year deal didn't he? How he could have thought this was a wise move escapes me, but to sack him now means he'll be paying two gaffers for years to come. But I don't know if there is a worse manager in the League. He has to go.
Newcastle may be a bit unbalanced, but they have some good players. With Pardew in charge though they will never improve. I'd sack him today. But who do you appoint? Curbishley is probably odds on at 5 to 1
