Zurich: Lionel Messi and Neymar will take part in a new anti-doping program to trial a biological passport in football, FIFA said.
All players set to be involved in the seven-team Club World Cup next month will give samples beforehand to help laboratories prepare their individual steroid profiles.
Players then selected for anti-doping controls in the December 8-18 tournament in Japan will have their results measured against out-of-competition tests taken up to one month earlier.
"(FIFA) recently reviewed the current drug-testing procedures within football and come up with a new approach," the governing body said in a statement.
"The main, new aim will be to capture players` individual steroid profile."
FIFA announced the pilot project as the competition draw featuring the six continental champions and the host nation`s league winner was made in Nagoya, Japan.
Teams including Barcelona, the European champions containing Messi, and Brazilian club Santos, the South American winners featuring Neymar, will have to provide details of their whereabouts for testers to collect samples.
"Every club will be required to provide FIFA with accurate details of their team activities (matches, training schedule etc.) during the period from Nov. 14 to Dec. 8," FIFA said.
While FIFA launched the passport program, a Real Madrid team doctor said yesterday that football should do away with in-competition doping controls, labelling them "ineffective" due to football`s set calendar.
