Sepp Blatter, the outgoing Fifa president, has insisted he has a clean conscience and that anyone who calls him corrupt should be sent to prison.
The 79-year-old announced last month he will step down following the corruption crisis that has engulfed the world governing body.
He told German magazine Bunte: "I have a clean conscience. If somebody accuses me of being corrupt, I ask him whether he knows the meaning of that word. Whoever calls me corrupt will have to prove it, but nobody can prove that because I am not corrupt.
"But if anybody calls me corrupt because Fifa is corrupt, I can only shake my head. Everybody who says something like that should go to jail."
