River Plate fans overcrowded a square in Madrid on Saturday, singing songs about their team, in the eve of the return leg of the Copa Libertadores final against arch rivals Boca Juniors.

The second match of South America’s most important club competition was originally meant to take place in River's home stadium El Monumental, however it was rescheduled and moved to Madrid due to attacks on Boca's team bus by rival fans upon its arrival to the stadium.
