Hazard, 26, has enjoyed an impressive return to form under Antonio Conte this season.
He has made 33 top flight appearances for the Premier League leaders, scoring 15 goals and assisting five in the process.
And Ferdinand reckons the Belgium international is the star man in west London, just as Ronaldo was for the Manchester United side he himself was a part of.
The former defender has revealed how Hazard left him bamboozled during his time as a player, telling The Times: “Hazard has improved his movement and, of course, he is Chelsea’s ace, just like Cristiano was ours.

“Playing against him, I found that when he received the ball his awareness of where people are was brilliant and his low centre of gravity meant he could roll people.
“Patrice Evra is small but a superb specimen who used to physically dominate wingers because of his strength, speed and low centre of gravity.
“But then he came up against Hazard and you were thinking, ‘Wow, this kid — you don’t want to be coming up against him too much, Pat.’
“Pound for pound, Hazard was the same shape, strength and size and he was rolling Patrice inside and outside.”
