El Clásico Nacional a.k.a. El Clásico de Clásicos is Mexico’s most important soccer game as it involves an old clash and rivalry of ideologies and identities dating back to the 50s.
On one hand, Chivas, the people’s team with only Mexican players in their roster as part of a long tradition, and on the other, America, the antagonist, the one with the financial muscle to buy foreign stars.
Their slogans confirm their own antithesis; Chivas is "El más querido" (The most loved) vs. America’s “Odíame más” (Hate me more).
Furthermore, they are Mexico’s two top teams in terms of Championships, fans numbers, shirts sold, and fans outside Mexico.
