At its executive committee in Paris on Monday, soccer's world governing body repeated its position that each doping case should be dealt with individually.

WADA agree with that, but insist on keeping the right to appeal against any decision taken on doping by FIFA which WADA feels is too lenient.

That is the sticking point which could prevent the agreement between FIFA, WADA and the IOC being signed at FIFA's Centennial Congress in Paris on Friday.

If that fails to happen, soccer's place in the summer Olympics is in jeopardy.

FIFA are the only major Olympic federation with the International Cycling Union (UCI) to have refused to sign WADA's anti-doping code because it imposes an automatic ban of two years for doping offences.
