Whether we like it or not, money is slowly but surely taking over football.
Clubs like Manchester City and Paris Saint-Germain are becoming mega-rich because of the endless stream of oil money being injected by Middle Eastern billionaires. It's sad, and a bit disgusting, but it's one of the changes that football is undergoing as it becomes more modern and it's something us football fans have to accept.
With all of that money comes huge transfer fees spent on players: the 80 million pounds spent by Real Madrid on Cristiano Ronaldo, or more recently the 50 million pounds that Chelsea spent on Fernando Torres. When a top club sells a top player, it demands top dollars, and that's something we see every transfer window.
Here are my predictions for the 10 largest transfer fees of the summer window, and keep in the mind that the predicted fees are rough numbers and not meant to be spot on.
