Once touted as a future FIFA president, Bin Hammam has vowed to step down from the AFC if defeated in this vote for the West Asia seat on the FIFA executive committee.
In his first challenge since taking a seat among FIFA's top decision makers 13 years ago, he is adamant he will prevail against Salman bin Ebrahim al-Khalifa, a Bahraini Sheikh backed by Bin Hammam's fiercest opponents.
"I am very confident going into the final stretch," Bin Hammam told Reuters in an e-mail interview.
"I have my record to run on, and I am proud of my record."
"I think the campaign could have been cleaner," he said. "I only wish we ran solely on our records, in which case I believe there would be no contest."
Bin Hammam is widely credited as a reformer of the Asian game but his critics accuse him of being a "dictator" with an authoritarian rule that has divided a region stretching 11 time zones.
"Asia is now an influential force in world football and this happened only after I joined the FIFA executive committee," Bin Hammam said.
"Our opinions are taken seriously and we are no longer considered lightweight."
Al-Khalifa, a member of the Bahraini royal family, insists he does not want his opponent's AFC job, just his FIFA seat, and has vowed to improve transparency in the AFC's financial dealings, attract greater funding and help bring either the 2018 or 2022 World Cup finals to Asia.
"I want change for Asian football," he told reporters this week.
"I am more assured of my ability and my chances are better than my opponent in the battle.
"The voices of Asia must be heard because Asia is right now divided because of the growing unhappiness."
