Who are the 'dubs'?

[englishhobby]

I can't find in any dictionary the definition of the word 'dub' that fits the following context (a person is describing a football match he took part in):
It's the seventh minute into a match and we're up against one of the top dubs in Britain.

Are you sure you didn't misread "clubs"? The combination of "c" and "l" together can look like a "d" in some fonts and sizes.

Thank you very much! Yes, I think it's clubs.
