I watch Premier League and Champions League only. I used to be a fan of AC Milan, still cheer for them whenever they play but I never watch them so I guess I cannot call myself a fan of AC Milan.
The advantage is that I have a pretty much objective view on anything and also that none will ever call me a plastic fan (lol).
“I used to be a fan of AC Milan”
“Nobody will call me a plastic fan”
Make it make sense.
