Michel Platini thinks FIFA must hold another vote for the 2022 World Cup if corruption allegations against Qatar's winning bid are proven.
The UEFA president told sports newspaper L'Equipe that he doesn't regret his own vote for Qatar and still thinks the Gulf nation "was the right choice for FIFA and for world football".
"But if instances of corruption are proved, there will need to be a new vote and sanctions,'' Platini said.
A FIFA prosecutor plans by next week to wrap up his investigation of the 2010 votes for Qatar and 2018 World Cup host Russia.
On a personal note, Platini claimed that "somebody, something'' is plotting to discredit his possible candidacy for the FIFA presidency.
Media reports this week cast doubts on Platini's links to now disgraced Qatari official Mohamed bin Hammam. London's Daily Telegraph alleged Platini had "a secret meeting'' before the 2010 vote with Bin Hammam, suspected of vote-buying and other irregularities and whom FIFA subsequently expelled in 2012.
Platini told L'Equipe it was simply breakfast with a work colleague. Bin Hammam, like Platini, was a member of the FIFA board.
"I saw this colleague 10,000 times in 15 years. Why would I have had a secret meeting with him? I now realise that in the background there is somebody, something, people organizing all this. I can feel it.''
