Leicester City boss Claude Puel is delighted for Eden Hazard over his success with Chelsea.
The Foxes chief gave Hazard his professional debut when he was a 16-year-old at Lille in 2007.
Puel could always see the player's ability when the pair were together at the Metropole.
"He is a fantastic player and he improves a lot," he said. "But he had the same quality at 16 when he started in the first team at Lille, it was the same.
"Of course now he has more consistency in his game but always he is fantastic in his play and has the ability and capacity to make good penetration and give good assists.
"Eden is a fantastic player but I wouldn't man-mark him.
"If we just keep concentration on Eden, other players can make the difference also. A good response is always a collective response with a competitive organisation."
