Joao Felix, Antoine Griezmann and Eden Hazard have all entered the list of football's most expensive stars following their moves ahead of 2019/20.
The former, who is said to be Portugal's best talent since Cristiano Ronaldo, joined Atletico Madrid for €126 million (R1.96 billion) from Benfica.
At Los Rojiblancos, he replaced Griezmann, who moved to FC Barcelona for €120 million (R1.87 billion), while Eden Hazard joined Real Madrid for €100 million (R1.56 billion).
While Felix and Griezmann's deals came about after their new clubs activated their respective release clauses, Hazard's transfer could still rise to €150 million based on performance based add-ons. He currently sits in tenth position among football's most expensive players, but he could move into third, if all add-ons were met.

Felix follows in fourth, ahead of Ousmane Dembele's €125 million (R1.94 billion) from Borussia Dortmund to the Catalan giants, which again has a package of performance-based add-ons on top.
