While the video itself feels like a reading of a Wikipedia page, I actually found out a few things about my favourite Italian club, Roma.
The rivalry is fierce. I saw Roma vs Juventus in Rome back in 2009 and it wasn't the type of atmosphere I'm used to watching Premier League football. The fans were aggressive and we left after 60 minutes. I'd highly recommend going to see a Serie A game, just not sure I'd be able to cope with the stress of watching a true derby in person.
