[Exile on Spencer St]

It's not Man Utd you should despise but certain types of so-called 'fans' that they attract. They 'support' brands like Man Utd in the same way that other people support Asda over Tesco, Samsung over Apple, or KFC over McDonalds. They are desperate to be associated with something that is seen as successful, thinking it somehow reflects on them. Pity, rather than hate, would be a better response.
What we need is another word than 'football fan' for those know-alls who never go to a match.
