Substitute Kennedy volleyed home from the edge of the area in the 99th minute of an ill-tempered final at Rio's Maracana Stadium after the match finished 1-1 after 90 minutes. Kennedy was promptly sent off for collecting a second yellow card for an over-exuberant celebration among Fluminense's delirious home fans following the goal.

The 21-year-old Kennedy named by his history-loving father after the 35th President of the United States had been a decisive influence for Fluminense after being brought on as a substitute for Ganso 10 minutes from the end of normal time. At that point, Boca looked to be getting on top after equalising with a 72nd-minute shot from Peruvian right back Luis Advincula which cancelled out Fluminense's 36th-minute opener from veteran forward German Cano.

But the arrival of Kennedy breathed fresh life into the Fluminense attack and in the first half of extra-time, the young made the breakthrough.
