In some ways, I'd love a big draw like Man City or Arsenal and we'd have a big crowd, possibly be on TV and get some money that might be spent before Friday on new players. Another part of me would love to get to the 6th round, as we've never done that since I've been watching so a home game against someone like Charlton or Sheffield Wednesday would be preferable (not that I guarantee we'll win, just that we'd have a better chance).
However, as a compromise, I've gone for Fulham (obviously assuming they can beat Sheffield United today). Would get a good crowd at a localish game with a fair chance of being on TV and a chance of winning.
Heart says Southampton away, it's a home away game for me and I'd love us to sneak a win to stop lots of my mates gloating about how they are 'back where they belong'
