Argentina's World Cup players have been given greenlight to have sex with their regular partners during the monthlong tournament.

Team doctor Donato Vallani told Argentine radio that sex was a part of life and would not be a problem.

"The players can have sex with their wives and girlfriends during the World Cup," Vallani said on Radio Del Plata. "Players are not Martians. But it should not be at 2 a.m. with Champagne and Havana cigars."

He also said drinking was prohibited but the players could eat Argentina's specialty with a glass of wine.

Argentina, qualified last in South American zone for the June 11-July 11 World Cup finals, travels on Friday to South Africa and plays Group B along with Nigeria, South Korea and Greece.
