Buenos Aires will once again come to a standstill on Saturday as River Plate host Boca Juniors in the second leg of the 2018 Copa Libertadores final at El Monumental.
A raucous first leg two weeks ago finished 2-2 at La Bombenera, and with the away goals rule not in play for the final, it could hardly be more finely balanced.
River do have the slight edge, though, given Argentina's visiting fans ban means the hosts will have the backing of the entire stadium on Saturday.
But that may simply pile more pressure on Los Millonarios' players in arguably the biggest Superclasico ever played.
