Hazard will be officially unveiled as a Real Madrid player on Thursday, June 13.
The Belgium captain scored 110 goals in 352 appearances for the Blues during his seven years at the club.
Fabregas, a former teammate with Hazard during their time at Chelsea, took to his official Twitter page to post about Hazard’s move, wishing his former team-mate success at his new club.
“Great moments on and off the pitch. It’s been a pleasure sharing all the good moments and specially the not so good ones that we overcame together over the last 5 years with the reward of winning it all. Enjoy your new challenge amigo! @hazardeden10”.
