in the Prem it's Spuds without question. they remind me of hi-so wannabes, and their fans often have the same bloated sense of entitlement as rags. i don't hate them even half as much as rags however.
i also have a deep loathing for AC Milan (this predates the recent fiasco, i've hated them since i started following football) and Real Madrid. i hate these two almost as much as rags.
i also hate P$V, but more because they're rivals to my other favorite (Ajax Amsterdam).
