FIFA when announced it will take out-of-competition blood and urine tests on 576 players before and during the World Cup. The 32 finalists have been told to ­submit their team whereabouts by 22 March. Without notice, eight players from each squad will be randomly selected during friendlies or training camps. Those tests will start on April 10 and run until June 10 , the day before the opening match of the World Cup.

There will also be drug testing during the tournament, said FIFA's chief medical officer, Jiri Dvorak, who added: "Two months prior to the World Cup we will be visiting the teams unannounced. During the World Cup, two players from one team will be selected randomly after a match.

"We have a strict strategy to fight doping and we take the fight against doping very seriously and are committed to continuing it in full compliance with the Wada [World Anti-Doping Agency] code. The teams have confirmed their full compliance in this regard."
