10 Most overpriced transfers of 2018

#1 Kepa Arrizabalaga

Kepa Arrizabalaga is easily the most overpriced transfer of 2018

Market Value: €20 million

Transfer Fee: €80 million

Difference: €60 million

In what was the most shocking transfer of the summer window, Chelsea activated Kepa Arrizabalanga's release clause at Athletic Bilbao for an extraordinary €80 million, making him the most expensive goalkeeper in the world.

Fans who do not follow LaLiga had probably never heard of Kepa, but Thibaut Courtois' move to Real Madrid forced Sarri's hand and he went straight for the 23-year-old Spaniard. The transfer fee ensured that the world record paid for a goalkeeper was broken twice in the same summer after Liverpool had bought Alisson becker a few weeks earlier.

Kepa has started all four of Chelsea's Premier League games this season, conceding three times. However, having moved to Stamford Bridge for a frankly ridiculous €60 million more than his market value, it will take many seasons of top-level performances to justify such a fee.
