Neymar — PSG €222M Transfer

Neymar's €222 million transfer to PSG in 2017 remains the most expensive in football history, yet it delivered only one Ligue 1 title that the club would have won without him—a league they had secured 6 times in the previous 11 years. Injuries limited him to 56% of possible games over six seasons, and his €47 million annual wage made him the highest-paid player in Europe, per L'Équipe, while his Champions League output—14 goals in 29 knockout matches—was outpaced by #5 Coutinho's per-game rate at Liverpool. The deal also triggered a spiraling market; his €222 million fee was 65% higher than the second-most expensive transfer, and PSG recouped just €90 million by his departure to Al Hilal.
