USA is the only squad I openly consider myself a supporter of.
However I do enjoy watching Arsenal, Liverpool, Spurs, Barcelona, Valencia, Athletic Bilbao, Sevilla, Real Madrid, Atletico de Madrid, Lazio, Roma, Napoli, Milan, Internazionale, Munich, Dortmund, Schalke, Hoffenheim, Ajax, Feyenoord, Marseille, Bordeaux, Lyon, Legia Warsaw, Red Star Belgrade. Not a comprehensive list, but these are all clubs that I admire for the way that play on the pitch, but in a few cases it's for cultural and historic reasons.
Clubs I don't like: PSG, Manchester City, RB Leipzig, Bayer (Monsanto) Leverkusen, Red Bull Salzburg, New York Red Bulls, NYCFC, St. Pauli FC, and Livorno - This is all based upon the ownership of these clubs, or their supporter culture.
