2.- Kylian Mbappe €180 million
This is where things get even trickier, mainly because PSG is the club that completely broke the market and turned it on its head.
They went after two of the most coveted players in the world during the summer of 2017, they couldn’t sign Mbappe right away because they spent all their money on Neymar.
However, the French giants reached a loan agreement for a year and paid for his transfer a year later.
They initially paid €135 million but there are €45 million left to pay, the grand total is the second highest amount paid for a single player.
