Boca Juniors captain Pablo Perez says he would have been fearing for his life if the second leg of the Copa Libertadores final had been allowed to go ahead.
The match - originally scheduled for Saturday - was pushed back to Sunday after the Boca bus was pelted with missiles as it arrived at the ground, with Perez among the players to sustain injuries in the attack.
A further postponement means the destiny of the fixture is uncertain and officials from CONMEBOL, Boca and River are all due to meet in Asuncion, Paraguay on Tuesday to discuss a new date – and potentially location.
