Banned former FIFA vice-president Chung Mong-joon has officially filed an appeal against his five-year suspension to the Court of Arbitration for Sport (CAS).
The South Korean official was exiled from the game for a six-year period in October 2015 after he was found guilty of infringing FIFA Ethics rules related to conduct, confidentiality, disclosure and collaboration following reports into the bid processes for the 2018 and 2022 World Cups.
The FIFA Appeals Committee then reduced his ban by one year in July 2016.
"Dr Mong Joon Chung has filed an appeal at the Court of Arbitration for Sport (CAS) against the decision issued by the FIFA Appeals Committee on 23 June 2016," a CAS statement read.
"In his appeal to the CAS, Dr Chung seeks the annulment of the decision taken by the FIFA Appeals Committee in which he was suspended from all football-related activities at national and international level for five years."
Chung, who had looked to run for the FIFA Presidency before his suspension, has regularly criticised world football's governing body since they took the decision to ban him.
Earlier this month, the multi-billionaire accused FIFA's Ethics Committee of "malicious behaviour" and claimed world football's governing body is still littered with officials still loyal to the disgraced Sepp Blatter.
He has also insisted his appeal to the CAS will be successful and has optimistically vowed to "clean up" the organisation should sport's supreme court rule in his favour.
Chung claims he has a strong case and has refused to give up the fight to clear his name.
The 65-year-old also called on FIFA President Gianni Infantino to take an interest in his appeal.
The South Korean feels Infantino can help lead the governing body out of a period of unprecedented turmoil but claimed "Blatter’s people are still on the Ethics Committee and Appeals Committee".
