El Clásico is the name given in football to any match between fierce rivals FC Barcelona and Real Madrid. Originally it referred only to those competitions held in the Spanish championship, but nowadays the term has been generalized, and tends to include every single match between the two clubs: UEFA Champions League, Copa del Rey, etc. Other than the UEFA Champions League Final, it is considered one of the biggest club football games in the world, and is among the most viewed annual sporting events. A fixture known for its intensity, it has featured memorable goal celebrations from both teams, often involving mocking the opposition.
