Hazard has wowed for Chelsea this term in their surge to the top of the Premier League.
The Blues made a dreadful defence of their title last term, finishing 10th in the top flight.
New boss Antonio Conte has shaken things up and got Hazard back in form after his slump last season.
“I’m quite tough on Eden Hazard, not because I dislike him, but actually because I think he’s an unbelievable player”
Man United legend Gary Neville on Chelsea star Eden Hazard
Neville is a big fan – and wants the Belgian to prove he’s a top drawer talent.
“I’m quite tough on Eden Hazard, not because I dislike him, but actually because I think he’s an unbelievable player,” the Manchester United legend said on the Gary Neville podcast.
“A player like him should be reaching the level of [Gareth] Bale, [Cristiano] Ronaldo, [Lionel] Messi.
“That is the level I would put him at. He cannot afford to have seasons like he did last year when you’re at that level, you have to build up a trust of being a world class player.
“World class isn’t just one season and then miss a season, it has to be every single season.
“The standard is higher now, the players like Bale, Ronaldo, Messi, they don’t drop, they’ve not dropped for seven or eight years, they’ve kept performing.
“What we’ve seen so far this season is a player who is devastating, and it looks like he’s back to his best.”
