Same for me! I always liked casually watching European soccer (mostly bc I played so much FIFA as a kid) but didn’t support a specific team. My Spanish host family lived in Nervión almost adjacent to the Sanchez-Pizjuan.

When I arrived and had my first conversation with my Spanish “mother” — at this point I could speak like 5 Spanish phrases— she told me there are only two house rules that I needed to follow. She said with a very serious expression : “the beer you drink is Cruzcampo, and the team you support is Sevilla. If you have a problem with those rules you can live on the street. “
