CONMEBOL has confirmed the second leg of the Copa Libertadores final will not be hosted by River Plate after an attack on the Boca Juniors team bus.

The statement was issued after a meeting in Asuncion between CONMEBOL president Alejandro Dominguez and River and Boca leaders Rodolfo D'Onofrio and Daniel Angelici, respectively.

CONMEBOL were quoted saying that "the violent events that put the safety of players, officials and fans at risk" are still being investigated.

Article 4 of the Libertadores regulations emphasises that CONMEBOL's objective is "to guarantee the principles of integrity, continuity and stability of competitions," as well as "equal opportunities, balance of disputes and the credibility of all those involved in the competition."

In a press conference after CONMEBOL made the decision, Domínguez remarked that the match will be played with security outside Argentina. "We decided that the match, if so defined, will be played outside Argentine territory," he said.

Likewise, CONMEBOL have resolved, according to the statement, that the return leg of the Libertadores final will take place between December 8 and 9, at a time and venue yet to be defined. Playing the match in the United Arab Emirates or in Genoa, Italy - a city with a clear link to both Boca and River - are two of the options on the table.

The organisation also guarantee "security coordination with the corresponding authorities," and will bear the travel and lodging expenses for up to 40 people per team.
