Manchester United legend Gary Neville has urged Eden Hazard not to relax at Chelsea.
"He now needs to push himself to a higher level," Neville wrote in his column for the Daily Telegraph.
"Hazard needs to bully defenders more, become a killer, somebody who gives full-backs nightmares before they play against him. And at 24, now is the time for him to make those improvements.
"When I watched the Chelsea-Manchester United game last Saturday, Hazard was head and shoulders above the rest, the outstanding individual, and he ultimately delivered the decisive moment by scoring the goal which won the three points for his team.
"He is a fantastic professional and, when I interviewed Jose Mourinho earlier this season, the mention of Hazard was the moment that brought a warm smile to Mourinho's face, with the Chelsea manager speaking of him being a really good professional and good person.
"And not only does Hazard have terrific match-winning qualities, he is also durable and anything but the definition of a flaky winger who goes missing from time to time."
