Shaikh Salman bin Ebrahim al Khalifa could make a formal announcement as early as Friday and would be a serious contender given his position as the leader of FIFA’s second-largest confederation.
A bid by the Bahraini royal would be another major blow to already suspended vice-president Michel Platini, whom he formerly backed for the FIFA job, and his Asian rival Prince Ali bin al-Hussein of Jordan.
FIFA has been thrown into turmoil with outgoing chief Sepp Blatter, former favourite Platini and South Korean candidate Chung Mong-Joon all suspended as corruption allegations engulf the world body.
Despite mounting sleaze claims and criminal charges against senior figures including Blatter, FIFA elections are still planned to go ahead on February 26 with Platini among the candidates.
The other potential contenders are a colourful and varied group including Brazil’s Zico, former FIFA deputy secretary general Jerome Champagne and South African anti-apartheid campaigner Tokyo Sexwale.
Shaikh Salman is also an unshakeable supporter of Qatar’s hosting of the 2022 World Cup, whose controversial bidding process was the subject of an internal FIFA investigation.
The Manchester United fan and one-time accountancy drop-out drifted between careers and even had a spell as a customs officer before turning his hand to football administration.
Backed by Kuwaiti power-broker Sheikh Ahmad al Fahad al Sabah, he won a landslide election in 2013 to succeed disgraced Qatari Mohamed bin Hammam as president of the Asian Football Confederation.
In April, he strengthened his grip when he won a fresh four-year term unopposed and became a FIFA vice-president — taking a post previously held by Prince Ali — into the bargain.
Shaikh Salman has thrived in his alliance with Sheikh Ahmad, who was elected to FIFA’s executive committee at the April congress and is also a major player in the Olympic movement.
The imposing Kuwaiti, a supporter of International Olympic Committee president Thomas Bach, heads the influential Olympic Council of Asia, which runs the Asian Games among other major events.
He is also president of the Association of National Olympic Committees, which has more than 200 members, and chairs the Olympic Solidarity Commission, which hands out grants for athletes and sports development.
