Warner, who resigned as FIFA vice-president in June a month after being charged with bribery, says even though he sat on the finance committee of the world governing body he was unable to discover Blatter's annual salary.

In a letter to the Trinidad Guardian, who have published the full text today, Warner said he would unleash his threatened "tsunami" of disclosure about FIFA once Mohamed Bin Hammam's appeal against his lifetime ban had been heard by the Court of Arbitration for Sport.

Warner said in the letter: "I will also tell you about the attempts I have made over the years, in my capacity as deputy chairman of FIFA finance committee, to find out the salary of Sepp Blatter.

"In spite of serving on the finance committee for over eight years, I have not been able, through the books or even through direct requests to him, to determine the quantum of money given to him for the office of the president of FIFA."

Warner, from Trinidad, said FIFA had failed to become a multi-racial institution, and claimed he would make revelations about Blatter's previous FIFA election victories in 1998 and 2002 when both he and Bin Hammam campaigned for the current president.

Warner and Bin Hammam were both charged by FIFA with bribery over a meeting in Trinidad in May when it is said cash gifts of 40,000 US dollars each were handed over or offered to officials from 25 Caribbean associations.

A video of Warner's speech when he appears to urge the officials to accept the gifts was provided to FIFA's ethics committee.

Warner added in his letter: "The vindictiveness of FIFA, not only against me but also against all others associated with me will be exposed. FIFA has tried to muzzle me with threats of a worldwide suspension.

"They have said that they will close down the FIFA development office in Trinidad by year-end. They have advised that they will terminate my son's 2012 contract at the end of this year.

"They have retaken the World Cup TV Rights first given to me by the former president of FIFA, Dr Joao Havelange, a matter for which they have not heard the last.

"They have refused to give me any of my 29-year pension. They continue to do such things like leaking a video in the hope that they can embarrass me to lie down on my belly.

"Never, I repeat, never, regardless of the consequences. Let me assure all that the promised tsunami will come."
