The Argentine legend made the sensational promise during a radio interview, five days after the two-time world champions had defeated Canada 5-0 in their last warm-up game.

When the reporter asked him how he would celebrate a World Cup triumph, Maradona said: "If we win the World Cup, I'll get naked and run around the Obelisk."

The Obelisk is one of Buenos Aires' most renowned landmarks. It's located in a crowded area at the center of the Argentine capital.

Forty-nine-year-old Maradona, who led Argentina to the World Cup title as a player in 1986, took charge of his national team late in 2008.

Argentina are regarded as favorites for the 2010 World Cup title. They lie in Group B alongside Greece, South Korea and Nigeria.
