Maybe the fact that there is no UK national team?

Edit: Frankly I don't care so much about karma, but this downvote is strange. I would have thought that this reason wasn't controversial at all. I've even heard british players say that. Anybody care to explain?

Not downvoting, but I think England on its own has what it takes to do well.

Of course, but a joint team would minimize luck's role. England won World Cup once anyway, didn't it?
