Hazard could have cost around €145 million: Reports
Hazard's contract ran one more year, allowing the club to extract big bucks for him.
He has reportedly cost Los Blancos around €100 million, along with €45 million extra.
As a result, he is their most expensive signing after Gareth Bale (€101 million, 2013) and Cristiano Ronaldo (€94 million, 2009).
He is their third signing of the season after Eder Militao and Luka Jovic.
Chelsea director respects Hazard's decision to pursue fresh challenge
"Although it is with sadness we say goodbye to Eden- and we made it absolutely clear to him the club wished him to stay- we respect the decision he has made to take on a new challenge," said Chelsea director Marina Granovskaia.
