The Blues secured an impressive 3-0 win over defending Premier League champions Leicester City at Stamford Bridge on Saturday, with goals from Diego Costa, Hazard and Victor Moses handing Antonio Conte’s men the three points.
The west London side have been criticised for their disappointing performances in defence in recent weeks in the absence of the injured John Terry.
Chelsea lost to the likes of Arsenal and Liverpool as they endured a stuttering run of form in the Premier League.
And speaking after Saturday’s win, Hazard stressed the importance Chelsea being solid at the back if they want to challenge for major trophies this season.
Speaking in an interview with Chelsea’s website, Hazard said: “Like against Hull City, when you don’t concede goals you know it is easier to win games.
“When you are strong defensively you bring confidence to all the team, and it is more easy to score goals.”
Chelsea now turn their attentions towards their crunch clash with Manchester United at Stamford Bridge this weekend in the Premier League.
