Really hope no one suggests resting key players here because.. you know, it's a cup competition, and that's the in thing to do.
We've got no EL until March, and very little to play for in the league. We should go as strong as we can (which, admittedly, isn't very strong) in the FA Cup games.
It's a shit show of a season so far. We at least need the positivity and momentum of reaching the later stages of still big competitions like the FA Cup and EL.
