Hazard has long been linked with a move to Real Madrid and Martinez believes now is the right time to leave.
He told El Larguero: "It could be the best time [for Hazard] to try something different.
"He is a player who has maturity and a lot of leadership. His play is based on talent.
"Hazard could carry a new project anywhere in the world. He is at the best moment of his career. He could fit in any team in the world.
