Birmingham , for me will always be our main rivals.
and without them in the prem, and wont be again for a while, if ever..... will make our next meeting with them that little bit more special as we havent played them for a good while.
Dont mind the albion if im honest. Though a lot of their supporters that grew up in the 60's, 70's &early 80's see us as the main rival instead of wolves.
