FIFA have insisted that there has been no indication of any match-fixing situations at the World Cup, following reports that they had in fact been warned about Nigeria.
The world governing body issued a statement after BBC Two's Newsnight programme reported that a UEFA investigator had warned FIFA before the tournament that the Nigeria team could be vulnerable to match-fixing.
The statement said: “What we can say is that at least until today, no information provided by informants to FIFA in relation to any potential match-fixing activities during the 2010 FIFA World Cup have proved to have any substance.
“Furthermore, we can also say that there is no indication whatsoever until today of any match-fixing situations during any of the matches of the 2010 FIFA World Cup.”
Newsnight reported that a UEFA investigator in South Africa raised concerns on the morning of Nigeria's first match against Greece that the players were “vulnerable to manipulation”.
The informant also alerted FIFA's new Early Warning System body of his concerns over betting patterns.
