Member of 2010 World Cup organising committee, 62
Seen as unencumbered by Fifa scandals, though it is unclear if the South African has enough support to stand.
PRINCE ALI AL-HUSSEIN
Fifa vice-president, 39
Jordan prince had lost to Sepp Blatter in May's Fifa presidential election. Not touched by scandal but ran a disappointing campaign against Blatter. Sheikh Salman will expect to take most of Asia's votes.
Former Fifa deputy general secretary, 57
The Frenchman tried to run against Blatter this year but failed to attract support. Styling himself as the "clean" candidate, he wants candidates to take part in debates.
SHEIKH SALMAN AL-KHALIFA
President of the Asian Football Confederation, 49
Criticised over allegations, which he denies, of abuses by a committee he is said to have chaired during 2011 demonstrations in Bahrain.
Uefa president (suspended), 60
Will be allowed to stand if he is not still suspended on election date. With an option of the ban being extended for another 45 days, the Frenchman has precious little time.
Uefa general secretary, 45
Uefa's insurance card. Seen as a shrewd operator, the Swiss has served as Platini's right-hand man at Uefa since 2009. Known best as the man who cracks jokes during Champions League draws.
Former Trinidad and Tobago captain, 51
Mostly unknown outside the Caribbean. Towards the end of his career, he played for disgraced former Fifa vice-president Jack Warner's club.
President of the Liberian FA, 48
Could be a powerful candidate if he can mobilise the Confederation of African Football, which did not support him in August.
