Do you know anybody who supports both sides of rival football teams?

I’m in Birmingham, which has arguably the biggest rivalry in England (not including Scotland of course.) My dad told me a while ago it was quite normal for people from the pub to go to both Blues & Villa home games on rotation so they went out every weekend. I think that probably changed in the 80s

I do think its a shame it’s as fierce as it is because PL tickets are so ridiculously expensive (£30 membership and £60-£80 depending on fixture) whereas League 1/Championship is much cheaper.

Anyway, do you know anybody who is fearless enough to go to both?
