In 1997, after a successful stint with Argentina's under-20 team, Riquelme was called up to the Argentina national team by coach Daniel Passarella for their last qualifying match for the 1998 World Cup on 16 November 1997. The match was played at the stadium of Boca Juniors, La Bombonera, where a 19-year-old Riquelme debuted for Argentina when he entered the field in the last minutes of the 1–1 draw against Colombia. His first major tournament for Argentina was at the 1999 Copa América.
