I've just skimmed the last few pages and for what it's worth (as a Dutchman) I always support England.
It's weird to support an English club and not have an affinity with the country it's based in.
Because of the anti-English sentiment from the other homenations and Ireland, I always find myself rooting against them. My friend's enemies are my enemies.
Perhaps worth mentioning, almost the whole of the Netherlands want England to lose, maybe even more so than Germany. So the English people might want to take this into consideration before feeling the need to support Holland in future tournaments.
