The final cost for the London Olympics came in at just under £9 billion and when we published that story back in October it certainly angered plenty of you.
However, that expense is nothing but a drop in the ocean when compared to just how much oil-rich Qatar is planning to spend on the World Cup in 2022.
According to Deloitte, the country is preparing to spend a quite staggering $200 billion (£134.3bn) – or roughly 15 times more than it cost London to host the Olympics.
The Deloitte report claims that $140 billion of that will be for transportation infrastructure including a new airport, roads and a metro system.
A further $20 billion will be spent on "tourism infrastructure"
The population of Qatar is under two million but they expect 400,000 people to visit the country during the World Cup.
FIFA's decision to award the World Cup to Qatar was controversial for a number of reasons - not least because temperatures in the tiny gulf state can reach more than 40 degrees Celsius in the summer months.
Historically, the World Cup has always been held in June and July and any change could lead to a major scheduling headache with the major European leagues normally playing through the winter.
Qatar's right to stage the 2022 World Cup if the event is moved to the winter months would also be open to a legal challenge.
The country is racing to develop efficient solar-powered cooling technology to counter the searing heat in their stadiums.
Qatar plans to construct its stadiums with modular technology so it can downscale them after the tournament, and donate seating to countries with little sports infrastructure.
