Toni Kroos-£443m
Toni Kroos is one of the best central midfielders in the world right now. His passing and vision is unreal. Real Madrid clearly pulled off a major coup in signing the German back in 2014 for a measly £20m from Bayern Munich.
The Real Madrid midfielder has a release clause of £443m million making him have one of the Top 10 Biggest Release Clauses in World Football.
Real Madrid slapped on the massive release clause when they extended his contract until 2022.
