Derby del Sol — Atletico Madrid vs Real Madrid

The Derby del Sol — "Derby of the Sun" — between Atlético Madrid and Real Madrid has grown from a domestic irritant into a globally significant fixture since Diego Simeone's transformation of Atlético. The clubs have met in two Champions League Finals (2014, 2016), both won by Real. Atlético represent the counter-cultural Madrid — the working-class foil to Real's galácticos. Their ability to consistently challenge the most richly financed club in football history, spending a fraction of Real's budget, has made this arguably football's most compelling David vs Goliath fixture.
