After both teams won one game each (by the same score, 1–0), Argentinos Juniors finally crowned champion in the playoff match held in Asunción. The Argentine side defeated América 5–4 via penalty shoot-out, therefore winning their first Copa Libertadores title.[2][3]
The finals was played over two legs; home and away. The team that accumulated the most points —two for a win, one for a draw, zero for a loss— after the two legs was crowned champion. If the two teams were tied on points after the second leg, a playoff in a neutral would become the next tie-breaker. Goal difference was used as a last resort.
I did not see the relevance of that achievement at the time. For me, it meant only one cup else because our team entered to the pitch to win whatever be at stake (...) For a club like Argentinos Juniors, winning a Copa Libertadores is very difficult. The club is not like Boca or River. And something similar happened when we won the Copa Interamericana. Who noticed that we won that cup at Trinidad and Tobago? Nobody.
