Daniel Passarella
Gallardo was considered for the Argentina national under-20 football team, but could not participate in the 1995 FIFA World Youth Championship in Qatar because Argentine national team coach Daniel Passarella wanted to include him on his squad (where he started at age 18 in 1994). He debuted in a 3–0 friendly-match victory against Chile in Santiago that year, substituting for Marcelo Espina.
