Neymar — Barcelona to PSG (2017) — €222 million

Neymar's €222 million transfer from Barcelona to PSG in August 2017 remains the most expensive in football history, costing nearly double the previous record of €105 million set by Paul Pogba. PSG activated his release clause with a single wire transfer within 24 hours—a feat that triggered a market-wide inflation of transfer fees across Europe. Although Neymar won Ligue 1 every season at PSG and scored 118 goals in 173 games, he never delivered the Champions League that justified the fee, leaving for Al Hilal in 2023 for €90 million. This deal outpaces #2 Mbappé's total package by €72 million, solidifying Neymar as the benchmark for inflated spending in modern football.
