Hazard is expected to move to Madrid this summer in a big money deal.
And Varane told Marca: "I've known him since I started at Lens. He is a top player and it's like I said to explain the case with Pogba, he could also play at Madrid.
"He is in the best moment of his career with the age and quality he has.
"When we [France] faced [Belgium] in the World Cup semi-finals we knew we had to have a special plan to stop him."
