Manchester City have spent huge sums of money since being taken over by Sheikh Mansour and the Abu Dhabi United Group in 2008.
Jack Grealish, Kevin De Bruyne, Riyad Mahrez and Erling Haaland are just a handful of names that have joined the club in massive deals in recent years.
Their spending has seen them become one of the world’s best clubs. While they haven’t won the Champions League, they are always in the latter stages and have been crowned English champions six times since 2012.
They aren’t the only club that have spent huge amounts of money in the 21st century, though.
Like City, Paris Saint-Germain and Chelsea were taken over by wealthy owners and have splashed the cash.
But which club have spent the most money of them all?
Transfermarkt have created a fascinating live graphic that shows the highest spending clubs in the 21st century.
The graphic starts in 2000, with Italian clubs dominating the highest spending clubs in the world.
