If you had to pinpoint two clubs who changed football with their spending you would probably pick Chelsea and Manchester City.
Since Roman Abramovich bought the club in 2003 the Blues have established themselves as one of the biggest financial players in the world and have become one of the most successful clubs in England.
Sheikh Mansour bought Manchester City in 2008 and they have matched Chelsea’s model, dominating on the domestic front and starting to go deeper in European competition.
The two teams go head-to-head on Sunday and we’ve picked out some transfers from both these clubs, just as a refresher of their financial muscle. All you have to do is pick which one you think cost more.
