5 Most expensive transfers of the summer window so far

#1 Killian Mbappe – Monaco to Paris Saint-Germain €145 million

Kylian Mbappe is unveiled at Paris Saint-Germain

Having spent a year on loan at Paris Saint-Germain, Killian Mbappe has finally made the transfer permanent with a €145 million move to the French club. In the process, he has become the second most expensive transfer of all time, behind teammate Neymar Jr., and the most expensive teenager of all time.

However, anyone who has watched Mbappe play either for the Parisian club last season or for France during the World Cup in Russia can see how devastating he can be. Pace, execution, strength, finishing, Mbappe has it all. It is no surprise that many are talking about the Frenchman as the player most likely to break the Ronaldo Messi grip on the Ballon d’Or.
