This rivalry is comparable to ... Real Madrid vs. Barcelona. Both teams have long, storied histories and the derby pits the capital against a side representing the provinces. As in Spain, the country sits up and takes notice when these two teams clash; both count on support from every corner of Mexico and into the United States.
Chivas, like Barcelona, have traditionally been the team of the people and a symbol of Mexican identity -- similarly to the Blaugrana's identification with Catalan nationalism. America, like Real, has plenty of working-class support, but also has all of the cosmopolitan swagger and aloofness that you would associate with the capital. Its name and badge allude to the American continent and while America is arguably the most supported club in Mexico, it is definitely the most hated. Las Aguilas fans even wear "Hate me more" t-shirts with pride.
Who will win? The big players
Joel Sanchez: One of a handful of players to cross Mexico's greatest footballing divide and appear for both Chivas and America, the Jalisco native did not enjoy his time in Mexico City. Sanchez lasted only a year with America before returning to Guadalajara in 2001. "El Tiburon" later admitted that he never wanted to play for America and only switched clubs because Chivas owed money to Televisa.
Cuauhtemoc Blanco: America's most revered icon is actually a homegrown talent. Blanco's childhood in the infamous Tepito neighborhood in Mexico City forged his crafty football skills and fierce temper. Throughout his career, the forthright forward was a major critic of Chivas. In 2015, he went on record saying he hoped the club went down when it was flirting with relegation.
