Former FIFA secretary general Jerome Valcke has launched an appeal against his 10-year ban from football-related activity with the Court of Arbitration for Sport (CAS).
Valcke was sacked in January 2016 as a corruption scandal engulfed football's world governing body, the 56-year-old having previously been suspended by FIFA's Ethics Committee.
The Frenchman was subsequently found guilty of a series of breaches of FIFA's code of ethics, including having conflicts of interest and offering and accepting gifts and other benefits.
He was initially handed a 12-year ban in February 2016, but that was reduced by two by FIFA's Appeals Committee last July.
Now Valcke - who has always maintained he has done nothing wrong - has taken his battle to CAS, aiming for "the sanction imposed on him to be lifted definitively".
Valcke's former boss an ex-president Sepp Blatter was also sanctioned by FIFA for ethics breaches, his attempt to overturn a six-year ban was rejected by CAS in December.
