Sepp Blatter and Michel Platini are facing likely bans of around seven years when FIFA's ethics judge delivers his verdict on Monday.
Barring a major surprise, both FIFA president Blatter and UEFA president Platini are expected to be found guilty of ethics code breaches surrounding a £1.3 million "disloyal payment" made to the Frenchman in 2011.
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 -- it was reported on Sunday that Blatter himself had claimed that those charges would be dropped.
