Eden Hazard — Real Madrid €100M+ Transfer

Eden Hazard’s €100 million transfer to Real Madrid ranks as football’s most disastrous investment. He scored just 7 La Liga goals in four seasons — a 92% decline from his Chelsea output — while collecting over €30 million annually in wages. That payout is 40% higher than the average European superstar salary, yet Hazard missed 82 matches through injury. His cost per goal: €14.3 million, 30 times more than the league average forward, making him 50% less efficient than even #5 Bobby Bonilla’s deferred deal.
