"Man City and Liverpool. They are both good. If we want to be there at the end, then we have to finish above them," Hazard told British media when asked which teams Chelsea will need to be most wary of in the title race.
Second-placed Liverpool overcame a stubborn Sunderland 2-0 at Anfield on Saturday, while City rallied for a 2-1 victory at Burnley earlier in the day.
Chelsea, who finished 10th last campaign, are in fine form, having scored 19 goals and conceded just one during their winning run and Hazard admitted the absence of European football had given Antonio Conte's side a vital advantage.
"We have one week to prepare for the game and at the end of the week, we know what to do when we play," the 25-year-old Belgian international added.
