River Plate made the sharper start at Estadio Monumental Antonio Vespucio Liberti and were rewarded early when the home side went in front at 7'41''. Flamengo answered before the half-hour, drawing level at 29'39'' and then completing a quick turnaround at 32'37'' as the visitors briefly took charge of the score.
That lead did not last long. River Plate responded at 37'26'' to make it 2-2, capping a breathless first half in which all four goals arrived before the interval. It gave the match its lasting shape, with the teams going into the break level after a wild spell of attacking football.
The second half could not match that tempo in front of goal. There were no further score changes after the restart, so the result remained 2-2 through full time. For anyone checking the stats, highlights and summary, the pattern was simple: a four-goal first half decided the feel of the contest, followed by a quieter closing 45 minutes in which neither River Plate nor Flamengo could force a winning finish.
