“It was a contract I had with Platini, a gentleman’s agreement,” the 79-year-old said in an interview with Swiss media RROTV.
“It was implemented. I can’t give any more details, the issue is being discussed in two investigations.”
Asked directly if the contract had been made within the rules, Blatter added: “Yes, certainly, it was within the rules.”
Blatter and Platini, 60, have both been suspended for 90 days by FIFA’s ethics committee as Swiss authorities conduct a criminal investigation into corruption allegations at the scandal-tainted world football governing body.
Blatter defiantly backed his right to discuss the ongoing controversy and investigation.
“I don’t have the right to go to a football stadium, but I do have the right to talk to whoever I want,” he added.
“I am not sidelined, I am only suspended.”
Blatter, who has been in charge of FIFA since 1998, still intends to be present when the FIFA congress meets on February 26 to elect a new president.
“My goal is to preside over the congress, that is my objective. I don’t believe it will be postponed.”
Blatter also blasted the international media for “pre-judging” him, saying his suspension had been a “shock.”
He added he was baffled by the decision to bar him from his office.
“I have not stolen, I haven’t killed, I haven’t favored anybody!”
The suspension, he said, had given him “time to think” and that he was “doing fine, even if it is a difficult period.”
