The Premier League champions came from behind to win 2-1 at La Liga giants Atletico Madrid in their second Champions League group-stage game on Wednesday night.
Marcos Alonso teed up Michy Batshuayi to score an added-time winner after summer signing Alvaro Morata cancelled out Antoine Griezmann’s penalty in the first half.
Chelsea are unbeaten in the Premier League since a 3-2 loss to Burnley on the opening day of the 2017-18 season ahead of the visit of Pep Guardiola’s all-conquering Manchester City team.
The Blues were 2-1 winners against last year’s runners-up Tottenham Hotspur at Wembley before a goalless draw with title rivals Arsenal at Stamford Bridge earlier this month.
Chelsea forward Hazard insisted that the defending champions will relish the chance to take on the Citizens in west London in their biggest game of the season so far.
“We are very confident, trust me. But also, Man City are very good so it is going to be a good game on Saturday,” Hazard said.
“Two great teams, two great managers, with a lot of good players on the pitch, so we will see. We want to play these types of games.
“We play for Chelsea, one of the biggest clubs in the world and we want to win every game.”
Chelsea won the Premier League title with two games to spare last season in their first campaign under Antonio Conte.
The Blues signed six players in the summer transfer window to bolster their squad ahead of a return to the Champions League.
