Yep, I understand this completely but think of the reward should we win. For me, beating them in the 4th round would not have any bearing on where the bragging rights reside, it's going to take a big game to get them back.
Really really don't want Palace, the 4th round is no way big enough a game to even get anywhere near expunging the memory of the Play Off game should we win, but the thought of being dumped out of the cup by them, especially if we're at home, does not bear thinking about.
Semi final or Final...
