I don't think we should 'try to win' the cup in the sense of making it the focus of our attention but if it happens as a natural by product of consolidating our position in the top 2 then, hey, why not win the damn thing...as long as it doesn't become a priority then there is every chance the positives will outweigh the negatives. (but let's not polarise the argument by saying there are ONLY positives or ONLY negatives of a prolonged cup run. It could work either for us or against us)
