Akhir 13, 1432 H/March 18, 2011, SPA -- Asian football chief Mohamed bin Hammam has confirmed he will challenge Sepp Blatter for the FIFA presidency, as AP reported. The Asian Football Confederation president ended months of speculation Friday during a news conference streamed online live from the confederation's Kuala Lumpur headquarters. The Qatari's announcement met an April 1 deadline to declare himself a candidate as he seeks to end his former ally Blatter's 13-year reign as the man running the world's biggest sport. He needs to be nominated by one of FIFA's 208 national federations, which will vote on June 1 at their congress in Zurich. Blatter has been nominated by Somalia.
