Hazard’s contract expires in 2020 and Chelsea are yet to tie him down to a new contract.
Madrid have been linked with the Belgian international for a while now and will be looking to poke him next summer.
Fabregas says although it was easy to fend of interests for Chelsea’s star man last summer, it would be more difficult next summer.
“It was an easy decision, especially now, because at this stage how much can Eden cost? Not many teams in the world can buy Eden Hazard. He still had two years left on his contract. Next year if he has one year left, that’s a different story. You don’t have as much power as a club. Eden is one of the best players in the world,” Fabregas told the Evening Standard.
“But having two years left, especially how the market is, it’s basically impossible to sign him up. I don’t think it was that hard from the club.”
Hazard Is having a fine season under new boss Maurizio Sarri and Fabregas feels he’s become a more matured player.
“I have had some great moments with Eden on the pitch but maybe in terms of maturity, yes it is the best [form of his career]. He has always had the ability but he is at an age now where he feels he can be more dangerous. He knows when to pass more, when to dribble.
“His maturity has improved a lot and now he is scoring goals, decisive goals, which we all wanted from him,” the Spaniard added. “When you see the top players, this is what they do. They make a difference in terms of scoring goals. I think he needed that to make the step forward and at the moment he is doing that so hopefully he can keep it up.”
