Zola was a fan favourite during his spell at Stamford Bridge and Di Matteo admits that he understands the comparison between Hazard and the Italian.
Gianfranco Zola was a wonderful talent, an artist, I would say," Di Matteo said. "Eden might become an artist as well. He's a talented man, a talented young boy. We'll have to see how he grows into a man and how quickly he will be an important player for Chelsea.
"You can see why people make the comparison with Zola because of the size. And we know about his technical ability, his dribbling ability too. We know he has that."
Zola made over 300 appearances during his time at Chelsea.
