In the 2000 Copa Libertadores, current champions Palmeiras were playing at home against Bolivian side The Strongest. In that cold winter night the Brazilians had no problems opening a big lead, and towards the end of the match, with favorable score of 4-0, Palmeiras's massage therapist asked the goalkeeper Marcos if he wanted some water. "Actually, bring me some coffee", he replayed. A few moments later goalkeeper Marcos was sipping some hot coffee mid Copa Libertadores match.
Obviously this was was seen as wildly disrespectful by all of Bolivia, however in Brazil the episode was toned down and justified by Marcos's addiction to the beverage and to his child-like innocence.
In Bolivia the second leg went very differently, The Strongest was able to get away with a 4-2 victory, and every single goal was celebrated by the Bolivians by sitting in a circle and pretending to drink coffee. These scenes are iconic in South America to this day.
The vengeance of the Bolivians didn't end there, just one year later Bolivia would host Brazil for the world cup qualifiers and again came out on top. Marcos was the starting keeper that night for Brazil, and a 3-1 victory for the home team had the crowd chanting "CAFECITO, CAFECITO, CAFECITO" (Little Coffee) every time the ball hit the net.
At the end, this international controversy was put to rest. Marcos never meant any harm and the Bolivian people got to poke some fun back at him twice. Regardless of anything, it was a historic moment in South American soccer history, so much so that Marcos reenacted the gesture during his commemorative retirement match and everyone got a good laugh one last time.
