FIFA presidential candidate Chung Mong-joon has vowed to sue Sepp Blatter in court for embezzlement and said world football's governing body "has become a corrupt organisation serving the interests of a few."

Chung, a former FIFA vice-president, said Blatter was being paid a secret salary that was not even agreed by FIFA's executive committee.

The South Korean told the Sport Leaders convention in London on Wednesday: "FIFA has become a badge of shame. To call it a mafia is almost insulting to mafia, so blatant and arrogant is its corruption.

"At FIFA, money and power have blinded Blatter in the virtues of sportsmanship.

"For his payment without executive committee approval, I plan to sue Mr Blatter for embezzlement in court. Mr. Blatter in short is a hypocrite and a liar.''
