Both maintain their innocence.

“President Blatter looks forward to the opportunity to present evidence that will demonstrate that he did not engage in any misconduct, criminal or otherwise,” Blatter's lawyer, Richard Cullen, said in a statement.

Platini also pledged to fight the decision, calling the allegations against him “astonishingly vague” in a statement sent from UEFA hours after the Frenchman was banned from working as the body's president.

“I want everyone to know my state of mind: more than a sense of injustice or a desire for revenge, I am driven by a profound feeling of staunch defiance,” Platini said. “I am more determined than ever to defend myself before the relevant judicial bodies.”

The statement from UEFA, which stressed “its full confidence” in Platini, has exposed the body's officials to potential action under FIFA ethics rules. According to UEFA statutes, Platini should have been replaced by Angel Maria Villar, the highest-ranking vice president.

“(Platini) is currently suspended and will therefore not perform his official duties for the time being,” UEFA said in a statement, still referring to Platini as president. “UEFA is fully aware of its responsibilities under the relevant provisions of the statutes.”

UEFA's 54 member nations are due to meet in Nyon, Switzerland, next Thursday to discuss the worst crisis in its history and the bid by Platini to succeed Blatter.

The 90-day suspensions for Blatter and Platini were imposed after the Swiss authorities started investigating a payment from FIFA to the former France midfield great in 2011 for work carried out at least nine years earlier.

Another presidential hopeful, Chung Mong-joon, was suspended for six years in a separate case and FIFA secretary general Jerome Valcke was banned for 90 days.

The suspensions can be extended by up to 45 days.

The International Olympic Committee called on FIFA to consider a "credible external presidential candidate of high integrity" as Blatter's replacement.
"Enough is enough," IOC President Thomas Bach said. "We hope that now, finally, everyone at FIFA has at last understood that they cannot continue to remain passive."

Issa Hayatou, the longtime head of the African soccer confederation who was reprimanded in 2011 by the IOC in a FIFA kickbacks scandal, took over from Blatter as acting FIFA president.
