Former International Olympic Committee director general Francois Carrard says he has been approached by Fifa to head its reform taskforce.
The 11-person panel will review football's scandal-hit world governing body.
Fifa has already said the chair of the group would be from outside the sport.
"I have been approached and I will make a decision next week," the Swiss lawyer, who was IOC director general from 1989 to 2003, told Reuters.
The remainder of the panel will be made up of members nominated by Fifa's regional confederations - two from the AFC (Asia), CAF (Africa), Concacaf (North, Central America and the Caribbean) and Uefa (Europe), as well as one representative from each of Conmebol (South America) and the OFC (Oceania).
Recommendations are due to be presented at the next meeting of Fifa's executive committee in Zurich on 24 and 25 September.
President Sepp Blatter's decision to resign announced on 2 June followed the arrest of seven Fifa officials as part of a United States investigation that saw 14 people indicted on corruption charges.
A separate criminal investigation by Swiss authorities into how the 2018 and 2022 World Cups were allocated is also under way.
