Three men remain in contention to challenge Sepp Blatter for the Fifa presidency.

Fifa's election oversight panel has confirmed that Blatter and three rivals - Prince Ali bin al-Hussein of Jordan, Michael van Praag of the Netherlands and former Portugal great Luis Figo - are now being vetted to become formal candidates after the close of nominations.

Fifa Presidents
Robert Guerin (France) 1904-06
Daniel Burley Woolfall (England) 1906-1918 
Jules Rimet (France) 1921-54
Rodolphe Seeldrayers (Belgium) 1954-55
Arthur Drewry (England) 1955-61
Stanley Rous (England) 1961-74
Joao Havelange (Brazil) 1974-98
Sepp Blatter (Switzerland) 1998-current

A potential fifth contender, former Fifa official Jerome Champagne, failed to secure the required five nominations. He said only three of Fifa's 209 member federations nominated him by last Thursday's deadline.

The four contenders will now undergo integrity checks by Fifa's ethics committee, and have their nomination papers scrutinised by the oversight panel.

The election panel expects to 'formally admit and declare the candidates who are eligible for the office of Fifa President' in about two weeks.

The election will be held May 29 at Fifa's congress in Zurich.

Blatter, who will turn 79 before election day, is seeking a fifth term in office to extend his 17-year reign.

The veteran Swiss official, who has worked for Fifa since 1975, is strongly favored to win. Uefa, which has 53 voting members, is the only one among six continental bodies actively opposing Blatter.

Prince Ali and Figo have been encouraged to run by UEFA and its president, Michel Platini, while Van Praag is a member of UEFA's executive committee. 

Van Praag has asked Blatter to step aside and has offered him an advisory role, including running a charitable foundation to give less privileged children opportunities in football.

Prince Ali, the FIFA vice president for Asia, is uncertain of widespread support in his home region. The Asian Football Confederation has long stated its support for Blatter.
