But who are the fanniest fans of them all?
1. Manchester United: The team has 659 million fans, according to the Guardian.
2. Dallas Cowboys: Jerry Jones has helped make football a religion in Texas.
3. New York Yankees: Other sports refer to their most dominant teams as “The Yankees of _______.” As in “Primorac Kotor are the Yankees of water polo.”
4. Washington Redskins: The team’s owner may be hated, but the team itself is wildly adored.
5. Real Madrid: This soccer club has one of the world’s most popular athletes, Cristiano Ronaldo, so it only makes sense that it would be among the most popular franchises.
