As much as some are saying the play first/second thing is important, I can't help thinking the first/second on the 'difficult games' is as much of a factor.
They have their run of what are described as their difficult games (Spurs and Chelsea) before ours (Palace away, Spurs and United). There's an overlap of a couple of hours, but that's all.
If they get through theirs then their tails will be up, and we will know there's no room for error. On the other hand, we may know they blown it and allowed a meaningful gap so the pressure's off.
