Uefa president Michel Platini believes that Qatar could lose the 2022 World Cup but insists that there is no chance of Russia being stripped of the 2018 edition.
There have been widespread calls for Qatar to be removed as hosts due to allegations within the British press of irregularities in the voting process - as well as player welfare concerns arising from the Arab nation's scorching summer temperatures.
Platini says that if the corruption claims are substantiated, there will have to be a re-vote, while he also acknowledged that Qatar 2022 would also have to take place in winter.
However, the Uefa supremo is nonetheless standing by his decision to back Qatar's bid.
"I have not been identified by the British press as someone corrupt," he told beIN Sports. "If there is corruption, there must be a new vote.
"I defended the new territories. The Arab world has lost the tournament vote seven times in a row.
"So, it's a good thing to give the World Cup to Russia and Qatar, though I will advocate for the competition to be played in winter.
"I have no remorse over my vote but we'll see what happens."
Russia's staging of the 2018 tournament has also been thrown into doubt by the political instability in neighbouring Ukraine.
However, Platini has dismissed the possibility of Uefa urging Fifa to either take the World Cup away from Russia or organising a boycott among other European nations.
"We have a big problem now with the Crimea and if politicians can not settle the issues there, how can Uefa?" the Frenchman asked.
"So no, we cannot remove the World Cup from Russia or boycott it.
"The proof as to why? The boycott of Olympic Games of 1980 did not change anything.
"You cannot penalise the 100 million Russians who love football."
