I'd just like to point out that saying that we should go there and beat them is not underestimating them, nor is it saying that it will be easy.
In my case it was merely a case of feeling that we're a superior team and that if we play like we should that we'll come away with 3 points. This is based on watching us, and them, this season.
That doesn't mean that we'll just turn up and win, or that we don't have to try, or that there's no way that we could not win, it just means that I think we should beat them. Which to be honest isn't a particularly outrageous, arrogant or naive thing to be saying.
