Here's what happens if River and Boca draw in the CONMEBOL Libertadores final

There's a huge difference compared to previous rounds in that away goals do not count.

In contrast to what happened throughout the previous knockout rounds, the away goal rule doesn't count in the final of the CONMEBOL Libertadores. This means if Boca and River are level on aggregate after 180 minutes, the team who has scored the most goals away from home won't be automatically crowned champions.

Another slight change is that two extra halves of 15 minutes will be played should the scores remain level at the end of the second leg.

And if the two sides remain deadlocked after those extra 30 minutes, the CONMEBOL Libertadores will be decided by a penalty shootout. The last time this happened was back in 2013 when Atlético Mineiro beat Olimpia.
