The first leg of the highly-anticipated Superclasico between Boca Juniors and River Plate in the Copa Libertadores final has been postponed due to a waterlogged pitch and heavy rain in Buenos Aires.
Dreadful weather in Argentina's capital cast Saturday's match into doubt and the postponement was confirmed around 90 minutes ahead of the scheduled kick-off time.
Boca and River will renew their rivalry on Sunday instead, with the match now set to get under way at 1600 local time (Monday 6AM AEDT).
Their clash will be the first Superclasico final in the history of the Copa Libertadores.
Both clubs triumphed against Brazilian opposition to reach the final, Boca knocking out Palmeiras while last season's champions Gremio were controversially beaten by River.
Gremio appealed to regional governing body CONMEBOL in the wake of their loss as River coach Marcelo Gallardo defied a touchline ban to address his players at half-time.
