Real said Hazard would be presented at the Bernabeu on Thursday after undergoing a medical in Madrid.
The rumours rumbled on and Chelsea manager Maurizio Sarri seemed resigned to losing Hazard following the club's final Premier League game of the season, insisting the club must "respect" the player's final decision.
Even though Madrid have craved Hazard for years, the Belgian's arrival is just one step in a huge rebuilding process being overseen by coach Zinedine Zidane, who has already signed Serbian striker Luka Jovic and Brazilian defender Eder Militao. His arrival takes Madrid's spending to around 300 million euros (340 million United States dollars) ahead of next season.
In an open letter to Chelsea fans published on his Facebook page, Hazard said: "You now know that I will be joining Real Madrid".
Eden Hazard has left Chelsea and moved to Real Madrid, in news that will shock absolutely nobody.
Eden Hazard leaving Chelsea as a legend!
"The memories he leaves us with will not fade".
Eden Hazard who is a Belgian Professional footballer, will be now known as a former player of Chelsea Football club.
An unveiling at the Santiago Bernabeu is expected next week, once Hazard returns from worldwide duty with Belgium, who play Euro 2020 qualifiers against Kazakhstan today and Scotland on Tuesday. "I hope that we are drawn against each other in the Champions League next season and every season so we can meet again".
Lyon left-back Ferland Mendy is also heavily rumoured to be on their wishlist as the club seek to bounce back from a disappointing campaign both in Europe and domestically.
Hazard's goals tally may not be at the level of Messi (who scored 51 times this season), but the pair, along with Neymar, are considered to be the best pure dribblers in world football.
