Juan Román Riquelme
Heinze participated in the 2007 Copa América, scoring with his head from a Juan Román Riquelme free kick in the semi-finals against Mexico, a 3–0 win for the eventual runners-up. In the 2010 FIFA World Cup he played in four of Argentina's five matches in South Africa, netting the game's only goal – his third international – in a group stage victory over Nigeria.
