Funes was a key player in the River Plate team that won the 1986 Copa Libertadores for the first time, in which he scored a goal in the first match in Cali, which River won by the score of 2–1 and at home in Buenos Aires, for the 1–0 victory against América de Cali.

[1] Ironically, this was not the first time Colombian teams and fans saw his moves; in the glory days of the Colombian league in the 1980s, Funes played for Millonarios, the team with the most championships in Colombia, where he simply "schooled" other forwards with his opportunistic technique and his attitude.

He returned to his homeland for a second time, being about to play for Boca Juniors but he finally could not debut with the team due to a heart failure detected by the doctors.

[3] He is considered today one of the great legends of Millonarios de Bogotá, and the River Plate fans remember his goals in the 1986 Copa Libertadores Finals.

Millonarios has one group of fans called Barra del Búfalo in honour of the idol of the club.
