Challenger to Sepp Blatter for the FIFA presidency, Jordanian prince and FIFA vice president Prince Ali bin al Hussein (C) leaves an hotel on May 27, 2015 in Zurich. Prince Ali called for urgent steps to end "the crisis" at football's world body after several leaders were arrested for corruption. Swiss police detained several FIFA leaders in a dawn raid as part of a twin corruption inquiry that rocked world football's governing body two days before its leader Sepp Blatter seeks a new term.
