Sepp Blatter has written to FIFA's member associations to tell them nothing can stop him from clearing his name.
The organisation's suspended president goes before its Ethics Committee on Thursday as he and UEFA boss Michel Platini answer charges over a £1.3m payment made to Platini in 2011.
The adjudicatory chamber of the Ethics Committee has the power to ban both men from football for life, and a decision is expected next week.
But Blatter maintains his innocence, a position outlined in letters to all 209 member associations ahead of his hearing.
In the letters the 79-year-old says he plans to look ethics judge Hans Joachim Eckert in the eye and ask him, "Why are you trying to destroy me?"
And Blatter has promised to carry on the fight to clear his name whatever the outcome, saying: "Nothing and nobody can stop me."
And in his letter he wrote: "I am bewildered by the insinuations and allegations brought against me by the investigatory chamber of the ethics committee.
"However the way in which the investigatory chamber of the ethics committee has communicated on the current proceedings, demanded the maximum penalty and reinforced public prejudgement has reached a tendentious and dangerous dimension.
"These proceedings remind me of the Inquisition.
"I will continue to fight for my rights and at the end of this week I will present my case before the adjudicatory chamber with great conviction and a strong belief in justice."
Blatter and Platini, who also denies any wrongdoing, are likely to escape lifetime bans for corruption but investigators expect the pair to receive lengthy suspensions of at least seven years.
They face charges including corruption, conflict of interest and non-cooperation. Blatter's case will be heard on Thursday with Platini's following on Friday, with a decision expected on Monday next week.
