Argentine football continues in 2021 with the playing of the Copa Liga Profesional play-offs.
All games are live streamed on Fanatiz and you can sign up to watch free here.
Boca was crowned 2019-20 league champions in March after coming out on top during the 23-game season, and also triumphed in the following Copa Diego Armando Maradona, which ended in January.
In lieu of beginning a new league season, the Argentine footballing authorities instead sanctioned another cup competition, which will run from February to May.
The 26 Primera Division clubs were split into two groups, with four teams from each qualifying for the quarter-finals of the play-offs.
And the last eight brought together Boca and River, with the Superclasico rivals meeting on Sunday at the Bombonera.
Fanatiz has the rights to the Copa de la Liga Profesional worldwide, excluding Argentina, Germany, Austria, Portugal, Israel, Russia, Sweden and the Balkans.
How to watch Boca Juniors vs River Plate
Boca performed a clean sweep in domestic competition over 2020 with league and cup wins, and once more started out as one of the favourites in this new tournament.
That success, though, was overshadowed by a disappointing exit from the Copa Libertadores at the hands of Santos, extending the club's drought to 14 years.
Miguel Angel Russo's men had few problems in negotiating their way out of Group 2, qualifying for the play-offs with a game to spare in second place behind Velez Sarsfield.
That set up a clash with none other than River, clinching the third Superclasico already in 2021.
River had to work a little harder to seal their spot, needing a victory over Aldosivi on the final day.
But they prevailed in style, thrashing the Tiburon to take third place in Group A behind Colon and Estudiantes.
