FIFA's medical chief says the swift action to submit the whole North Korea squad to anti-doping controls at the women's World Cup showed football's commitment to the fight against drugs.

Michel D'Hooghe said FIFA anti-doping doctors were called up at short notice from across Germany to submit all North Korean players to tests after two returned positive samples during random controls earlier in the tournament.

''We really lived by the rules and it should improve our reputation,'' said D'Hooghe told The Associated Press in a telephone interview.
