Last month, FIFA president Sepp Blatter admitted that choosing "high-risk" Qatar as the host of the World Cup was a "mistake," and the international federation is currently performing an investigation into possible corruption surrounding Qatar's successful bid.

So far, five of FIFA's six main sponsors have publicly issued statements of concern relating to the Qatar bid, with Visa's Chief Marketing Officer Antonio Lucio stating that he would expect FIFA to take "aggressive action" if any of the claims proved to be true.

Meanwhile, Qatar has denied any wrongdoing, including claims of bribery. FIFA's report is set to come out next month.
