One of the non-sporting highlights of the Olympic Games is the camaraderie we see between athletes of different nations - whether it be a congratulations after a tough battle or a helping hand when an opponent hits the deck.
But Argentina won't be winning any medals for sportsmanship this year, after an unprovoked attack from one of their field hockey players at the end of a game against Spain.
The game itself ended in a 1-1 draw, and Spain's David Alegre finished the match lying on the field as Argentina's Matias Rey came over to help stretch out his tired muscles, the two rivals seemingly in good spirits.
Cue Lucas Rossi.
