Former Chelsea defender Mario Melchiot has warned Chelsea about the dangers of letting Eden Hazard leave the club.

Hazard has a little over two years left to run on his current Chelsea contract and the Real Madrid are reportedly interested in the 27-year-old.

“Hazard is back to his best. He is playing amazingly and was unbelievable against West Brom yesterday,” Melchiot told talkSPORT.

“Can they keep hold of him? It’s going to be a big loss if they let him go.

“If you let Hazard go, who else will want to come and play for Chelsea?

“He is their top player right now and top players attract top players.

“They have to do something to make sure they keep hold on him, so they can move forward and build, because Hazard is definitely key to this team right now.”
