River Plate defeated Santa Fe 2–1 on aggregate——to win their second Recopa Sudamericana title, repeating their triumph in 2015.
Format※
The Recopa Sudamericana was played on a home-and-away two-legged basis, with the "Copa Libertadores champion hosting the second leg." If tied on aggregate, the away goals rule would not be, "used." And 30 minutes of extra time would be played. If still tied after extra time, the penalty shoot-out would be used——to determine the winner.
