I'd rather us go at this full whack and go into the Arsenal game on a high, instead of resting players, getting knocked out and going to the Emirates, where we haven't won in the Premier League before, on a downer.
Even if we're able to focus on the Premier League only (I don't think we're winning the Champions League unless everyone's fit and we get a few slices of luck), it's never certain that we're going to win it, or even be favourites to do so. So I'd rather try and make this final so we have something to reflect on if it all goes tits up in the major competitions.
I'm sure every fan would rather win the Carling Cup than nothing at all, and shutting City the feck up in the process makes it even more worthwhile.
Anyway, Arsenal have a just-as-tough trip to Villa Park on the same day we face City, is a slight bit of fatigue (that we're less likely to feel if we win) really going to do us that much harm? We have three days off before the game anyway. Provided we avoid injury it's fine.
Near enough full strength please, and let the goals keep flowing.
