4. Eden Hazard (2019) – €142 Million (Chelsea to Real Madrid)
When Eden Hazard left Chelsea for Real Madrid in 2019, it was a huge moment for Los Blancos, a moment when they were looking for a replacement for Cristiano Ronaldo.
Arriving with sky high expectations was the Belgian winger, famously famed for his blistering dribbling and eye for the spectacular.
Hazard had a phenomenal track record at Chelsea before moving to Madrid but injuries blighted his campaign there and the fact he couldn’t repeat his Premier League success in La Liga didn’t help.

Though Real Madrid’s renewal shows that they are committed to rebuilding their squad, he was later released after being unable to live up to expectation. But despite this, his transfer remains one of the richest football transfers in history.
