Nonsense. We were buried under Lampard, and results are much better with mostly tougher fixtures under Dyche. Bournemouth home will only be the second home game we've had against a bottom half side under Dyche: Lampard pissed away almost all of our easiest opportunities to rack up points with losses to the likes of Leicester, Southampton and Wolves at home.
You don't think staying up will have anything to do with Dyche? Nothing to do with beating Arsenal at home? Nothing to do with beating Brighton 5-1 away? Nothing to do with grinding out points against Chelsea and Spurs when under Lampard we'd have thrown in the towel? He's not been perfect, but in terms of what's achievable with the squad of players we've got I'm not sure anyone else does much better.
