FIFA's secretary general has floated an idea for a possible change to the World Cup bidding process in response to a spate of challenges in organizing next year's tournament in Brazil, which he says has "clearly" proven more difficult than in prior host nations. Valcke told reporters at a briefing in Rio de Janeiro on Wednesday he would like to see the highest-level political approvals required as part of the bid package for countries hoping to host future World Cups.
