He first played football for local club Huracán de San Luis, then
Estudiantes de La Plata,
Sarmiento de Junin, Jorge Newbery and
Gimnasia y Esgrima de Mendoza, and then for Colombian
Millonarios FC in 1984. In that year, his team became runner-up of
Colombian Primera A, and the following year he achieved a record 33 goals in a single season. Nowadays, he is one of the most iconic idols of the club.
River Plate 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. 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.
Olympiacos After his tenure on River Plate, Funes moved to Greece where he played for
Olympiacos. With the
Piraeus club Funes scored some very important goals (2 goals in the 1988
Greek Cup semifinal against
OFI, scoring 10 goals in 29 appearances).
Vélez Sársfield 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. Despite that, Funes did not end his professional career, joining
Vélez Sársfield. However, his health forced him to retire shortly afterwards. 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. ==International career==
