A member of FIFA's Executive Committee believes Qatar will be stripped of the 2022 World Cup because of safety concerns relating to the soaring heat.
Speaking to German publication Bild, former president of the German Football Association Theo Zwanziger said: "Personally, I believe that the World Cup will not take place in 2022 in Qatar."
The world's biggest sporting event was controversially awarded to the desert country in December 2010, and would represent the first major sporting spectacle hosted anywhere in the Middle East.
Football's world governing body FIFA have since been widely criticised for awarding Qatar the tournament, typically hosted in June and July, when temperatures in the Arab state average at around 50°C.
"It may be possible to use special cooling techniques in the stadiums, but the World Cup will not only take place in the stadiums," Zwanziger explained.
"Fans from around the world will be coming and travelling in this heat and the first life-threatening case will trigger an investigation by a state prosecutor."
