The Belgium international feels the current Chelsea boss's experience of playing at the highest level gives him an edge in terms of player relationships
Mourinho's time at Chelsea came to an end before Christmas last year after his team lost nine of their opening 16 Premier League games with the Portuguese tactician's relationship with key players, including Hazard, coming under the spotlight.
Hazard's form dipped in 2015-16, but he has started this season under Conte on fire with two goals in three league games.
Speaking to L'Equipe, Hazard said: "Conte puts trust in his players and now we are good after an ugly season last year.
"I've always been the same player but Conte knows how to treat players having played at the highest level himself."
Now at Manchester United, Mourinho's men – like rivals City and Chelsea – have won all three Premier League games to start the campaign.
