Last time out, Aldosivi lost 2-1 at home to Rosario Central, but they still were able to advance in this competition thanks to their 2-0 away win in the first leg. However, it was a poor campaign for El Tiburon in 2019, having claimed only three victories in a total of 13 games in all competitions (four draws, six losses). Aldosivi won only one of their last five home games, drawing two and losing two.
Three weeks ago, River Plate lost 3-2 to Tigre at home in the last league round (playing with a completely alternative XI), but they still secured a ticket for the 2020 Copa Libertadores, ending up the season in the fourth spot. Since then, the team won all three games over Alianza Lima from Peru at home (Libertadores, 3-0), fifth-tier side Argentino Merlo (Copa Argentina, 3-0) and Palestino away (Libertadores, 2-0 on Wednesday 24). El Millonario lost only one of their last 17 competitive games, winning 11 and drawing six.
River has scored in their last 14 league games plus 4 of their 5 Copa Libertadores games, Aldosivi can be dangerous in attack, so I can definitely see at least a couple of goals here.
