An anti-doping team has been making unannounced visits to clubs like Champions League winner Bayern Munich, as part of FIFA's efforts to create blood and urine profiles of the world's top players before next year's World Cup.
According to Sport24, the tournament in Brazil in 2014 will be the first World Cup where FIFA uses the athlete biological passport, the system that helps detect illegal substances from changes in a player's blood profile.
FIFA also will be one of the first federations to introduce the new urine profiling technique to detect steroids, announced as ready to go as an addition to the biological passport by the World Anti-Doping Agency this week, the report said.
It will cost FIFA close to 1 million dollars to introduce the profiling for the World Cup, the report added.
