It is being billed as the biggest match in football history and hyperbole aside it is almost unfathomably huge. Two of the fiercest rivals Boca Juniors and River Plate meet for the first time ever in the Copa Libertadores final vying for continental supremacy and they do so in Buenos Aires, the last chance to do so before the tournament moves to a one-off final hosted elsewhere.
Since the semi finals or even earlier when both clubs were in opposite sides of the draw, the prospect of a potential Superclásico in the final has been a tantalising one. A game that brings excitement and fear in equal measure and as a result makes for compulsive viewing.
River Plate overcoming Grêmio and Boca Juniors defeating Palmeiras set the final and immediately the drama began.
Grêmio, upset that River manager Marcelo Gallardo had flagrantly ignored his coaching ban by visiting the changing room at half time, appealed to CONMEBOL to have the second leg result overturned.
