The 38-year-old believes it would be “beautiful” to see his country become world champions and he is upbeat about their chances of winning Fifa’s prestigious competition
Despite being one of the traditional powerhouses of international football, the South Americans have not lifted the trophy since 1986.
Crespo, a part of three Argentina squads that tried and failed during the intervening years, is hoping the class of 2014 can emerge triumphant - although he admits they would require a hasty exit from the country of their fierce rivals should they achieve the feat.
"If Argentina win the World Cup in Brazil, I advise them to have a helicopter nearby because they're going to get killed," the former striker joked.
"It would be beautiful. Argentina's a great team but it's been a while since they have made it to the semi-finals [24 years].
"We should understand that we're a very good team, that we have a chance but that we've only won two World Cups."
A major reason for Argentine hope is the presence of Lionel Messi, who many hope can add to a glittering CV by captaining his country to glory.
Asked if it will be Messi's World Cup, Crespo replied: "God willing. Hopefully."
Argentina have been drawn in Group F alongside Bosnia and Herzegovina, Iran and Nigeria.
Their first game will be against Bosnia and Herzegovina in Rio de Janeiro on June 15, before they face Iran in Belo Horizonte on June 21 and Nigeria in Porto Alegre on June 25.
