Fluminense twice came from behind to share the points with Argentinos Juniors in the Copa Libertadores on Wednesday.
In the opening Group 3 clash, the two sides battled to an entertaining 2-2 draw at the Estadio Olimpico Joao Havelange.
Juniors attacker Franco Niell gave his side the lead on the stroke of half-time with his 44th minute goal.
Rafael Moura hit back for the hosts to restore parity after 58 minutes but Fluminense could not prevent Niell from grabbing his double with 20 minutes remaining.
But just as the visitors looked set to give their campaign a perfect start, Moura struck his second to ensure a share of the spoils.
It was Moura's fourth goal in as many days for his new club after joining from Goias.
