Moving the second leg of the last over 6,000 kilometers to Madrid is”robbing the fans”, states River Plate boss Marcelo Gallardo.

Gallardo’s side drew 2-2 with Boca Juniors in the first leg, however, the return game between the nightclubs was postponed after River lovers attacked the Boca team bus.

River have compared the switch to ’s Bernabeu, in which the game is supposed to be performed on Sunday.

The assault before the scheduled second leg at River’s Monumental stadium on 24 November abandoned a range of players reportedly experiencing dizziness and vomiting, and requiring treatment from club doctors.

“We’ve lost home advantage,” said Gallardo, after his side beat Gimnasia La Plata 3-1 in a league game on Monday.

“Some day we are going to rethink what happened and we’ll recall it as a total disgrace.

“Our preparations have shifted. We’re going to play 10,000 kilometres off. The of America. They have robbed the lovers.”

Each team will get 25,000 tickets for Sunday’s game, but just 5,000 of them can be sold to fans inside Argentina.

This is intended to protect against the infamous barra bravas, the frequently violent organised enthusiast groups, from travelling to see the sport in Spain.

The Argentine authorities said on Monday it was working closely with its Spanish counterparts to neuter the barra bravas and guarantee travelling fans would be kept aside in Madrid.
