Suspended Fifa president Sepp Blatter has compared the investigation into ethics charges against him to "the Inquisition".
Blatter, 79, made the claim in a letter sent to all 209 national football associations reiterating his innocence.
The Swiss was banned for 90 days in October, along with Uefa president Michel Platini. Both deny wrongdoing.
Blatter and Platini, 60, will have personal hearings with Fifa's ethics committee this week.
World football's governing body is investigating allegations that a £1.35m payment was made in 2011 for work Platini did as Blatter's adviser.
The term Spanish Inquisition is colloquially used to describe being asked questions which those facing them do not feel they need to answer.
