German judge Hans-Joachim Eckert, the chairman of FIFA`s adjudicatory chamber, held disciplinary hearings for the pair last week and is due to announce his findings and any sanctions on Monday morning.
Ethics investigators accept that proving corruption, which carries a lifetime ban, will be difficult -- with Blatter himself claiming at the weekend that those charges would be dropped.
"The judge told me at the start `the corruption charges have been withdrawn," the 79-year-old told Swiss newspaper Blick on Sunday.
According to PA Sport, investigators are very confident that other charges including conflict of interest, false accounting and non co-operation -- or criticism of the ethics committee -- will be proved. A file running to more than 50 pages was submitted by investigators.
