Scenes! Capacity Crowd For A Boca Juniors Training Session - Thousands More Are Locked Out!
The stadium was packed with noisy, passionate supporters who had turned up to give their heroes some encouragement - turning the atmosphere into a cup final.
The club's official Twitter had to post a message apologising to fans locked outside: "The stadium is already full to encourage our players. Our apologies 🙏 to all who will not be able to enter, but we are so many millions... Thank you!!!"
Screens inside the stadium relayed messages of support that had been submitted by fans and every video was cheered to the rafters.
The first leg of the final ended 2-2 and was an absolute thriller from start to finish. It had to be put back a day because of heavy rain in Argentina.
Ramon Abila gave Boca the lead ahead in the 34th minute but Lucas Pratto equalised for the visitors less than two minutes later. Boca were 2-1 up when Dario Benedetto scored just before the break but Carlos Izquierdoz scored an own goal in the 61st minute to leave the tie all square.
The second leg of the final takes place at River’s Monumental stadium on Saturday.
It is the first time Argentina’s two biggest clubs have faced each other in the Libertadores final. Away fans are banned from derby games in Argentina because of violence so Boca played the first leg in front of their own fans in a sold-out Bombonera stadium.
River coach Marcelo Gallardo was absent from the stadium because he was banned for ignoring a suspension during the semi-final win over Gremio.
