I really would like to know how Qatar got the World Cup… it can’t have been legitimate, it’s just got so many obvious disadvantages… For example, it’s too hot to host it in summer as usual, so it’s in the northern hemisphere winter, which interrupts all the leagues.
Bribes, some of which came out and are currently under investigation/prosecution.
Other reasons why it's a terrible idea: they have a small population, little football culture (in terms of absolute size), no infrastructure (all the stadia are newly built and some will be demolished afterwards; there aren't enough hotels); they have many laws incompatible with what usually happens at World Cups. There literally isn't a single positive thing to be said about Qatar hosting the World Cup.
That makes it a great airport hub, but it doesn't have the infrastructure to host, feed, transport, place in a stadium the hundreds of thousands of fans that want to watch a World Cup.
