Of his goal, the FC Porto loanee said: "[Camilo] Mayada gave me the ball, I looked for space and was then able to put it in the net."

Sunday's game took place amid heavy security with around 4,000 police deployed in and around the Bernabeu, more than the number used for a clash between Barcelona and Real Madrid.

However fears of violence quickly subsided as rival supporters mingled peacefully before the match and sat side-by-side with each other inside the stadium - an unthinkable occurrence in Argentina, where away fans have been banned from attending matches in the top division since 2013.

Boca had requested that the clash be canceled, arguing that River should have been expelled from the competition following the violence scenes.

But their apparent unwillingness to play was not evident on Sunday and Guillermo Barros Schelotto's men looked the most eager of the sides in the early minutes.

Pablo Perez had the first chance of the match, firing an acrobatic effort straight at goalkeeper Franco Armani in the 11th minute after Lisandro Magallan headed the ball down from a corner.

Perez frittered away another golden chance just before the half-hour mark when his partially deflected shot flew wide after a Benedetto set piece ricocheted off the River wall.

Boca were finally rewarded for their dominance as they broke the deadlock on the stroke of halftime.

Nahitan Nandez initiated a swift counterattack by bursting out of defense and threading a sublime 30-yard pass into the path of the onrushing Benedetto. The former Tijuana forward skipped past Jonatan Maidana before coolly placing his shot into the bottom left corner of Armani's goal.
