In an interview with Reuters this week, the 76-year-old Swiss, whose organisation was battered by a series of scandals last year, said he was hugely optimistic that delegates would see how far matters had improved a year into his fourth term.
"I am an optimist," Blatter, who was re-elected in June for what he says will be his final term, told Reuters ahead of the congress.
"I am sure you will see at the congress that we are back in the harbour, not heaven yet, but we are taking more people on board and are heading to calm, clearer waters."
Blatter originally set a two-year "road map" for reform, but FIFA would seem to be ahead of that schedule following recommendations made by the Independent Governance Committee (IGC) working under the governance expert Mark Pieth.
One of the key changes is that FIFA's Ethics Committee is being split into two with an investigatory body and an adjudicatory body dealing with contentious issues. It will also approve the setting up of a new Audit and Compliance Committee under the chairmanship of Domenico Scala, a Swiss-Italian business and legal expert.
The congress will also co-opt the first woman, Lydia Nsereka, in FIFA's 108-year history to the executive committee. She is the Burundi FA President, a member of the International Olympic Committee and also sits on Pieth's IGC body.
"I am very happy that some of the main points I mentioned last year, including the two-part Ethics Committee, are now the crucial point in the recommendations made by the IGC," Blatter said.
As well as changes to FIFA's statutes, the congress is also expected to welcome the newly-independent state of South Sudan as FIFA's 209th member association.
