Oh yeah, international football. Forgot that exists. Argentina, then.
As for clubs I sympathize with, I would give a shoutout to Borussia Dortmund. I care more about them than anyone else.
A South American... forgetting that international football exists.... like 3 weeks before the World Cup starts. Wow!
+1 to Borussia Dortmund sympathy though. For starters their yellow/black kits always look awesome, those colours work great together and really stand out from the red/blue/white monotony, but also, they're not Bayern which is a huge plus!
