Boca Juniors fans have arrived in Madrid ahead of the second leg of the Copa Libertadores final against River Plate on Sunday.
The Boca supporters were in jubilant mood and were seen banging drums and waving the club's flags.
The final was moved to Real Madrid's stadium, the Santiago Bernebeau, after Boca players were hurt when their coach was attacked by River fans as it approached the ground on November 24.
This resulted in the second leg being postponed and moved to Madrid.
The two sides drew 2-2 in the first leg on November 11 at Boca's ground La Bombonera.
Around 4,000 police, security guards and stewards will be on duty at the Bernabeu to ensure there is no trouble.
River will celebrate their victory at the city’s Puerta del Sol square which is traditionally the scene of the city’s New Year’s celebrations. If Boca win they will celebrate a mile down the road at the city’s Plaza Colon.
Boca say they should have been awarded the title - South America's equivalent of Europe's Champions League - as a result of the violent attack on their players.
