Which is the best South American team ever?

Atletico Nacional  is the only Colombian side on this list but deservedly so, considering the amazing feat they achieved in the 1989 edition of the Copa Libertadores.

Boca Juniors is the most succesful Argentian team in the Copa Libertadores, having won the title on no less than six occasions, four of which since the turn of the century.

River Plate are of course Boca's arch-rivals in Argentina and while they famously won the Copa Libertadores in 2015, it was their first success in the competition since 1996. 

Penarol is arguably Uruguay's most famous club on the international stage and its trophycase includes five Copa Libertadores trophies, albeit three came about in the 1960s and the other two in the late 1980s. 

Nacional, the second represantive of Uruguay in this elite company, has won the Copa Libertadores on three occasions but the most recent success came in 1988.

Olimpia is the only team from Paraguay to make the list and certainly the most successul at international level, as they are the proud holders of three Copa Libertadores trophies.
