Difference between Palace and Burnley is that Palace are pretty much set up to nick a goal and then defend extremely deep and have been doing so in the league effectively for a while, I can't see them losing that even with Pulis gone unless somebody comes in and reinvents the wheel (which would be foolish). Burnley won't have anything like the defensive organisation to pull that off (Pulis was pretty much the master at that, and although Dyche is clearly a competent manager this is a step up for him) and I'd say their squad is weaker than Palace's as well. They'll need a miracle to be honest, they don't have much money and have come into the league at a time when even the lesser teams can spend a fair amount. I can't say with confidence they are stronger than one team in the league let alone 3. Their only chance is to make Turf Moor a fortress, it's been a tough place to play in the past. Can see them putting up some initial resistance but falling away towards the end of the season.
