The World Cup has survived a rocky beginning, several last-minute rearrangements and a world war, yet now looks to be in more jeopardy than ever. The recent FIFA arrests and subsequent allegations of corruption have rocked football to its very core, throwing the fate of the 2018 and 2022 tournaments into serious danger.

The scramble would then begin to find a suitable nation to host either competition - but which are best suited in the event of such a logistical emergency? Thankfully, football's global appeal and long history means that there would be no shortage of suitors eager to step in, although the suitability of each candidate would certainly provoke mass debate.
