Paulinho – €80m
No, not the midfielder that used to play for Tottenham and Barcelona, but the 22-year-old who is currently plying his trade at Bayer Leverkusen in Germany.
The Brazilian was recruited for €20m in 2018, but he hasn’t hit the heights expected of him. Nobody will be looking to pay his release clause, though, as he could move on a free transfer next summer when his contract expires.
