Hazard thinks Chelsea, back in Europe after a season's absence, are as good as last season when they won the title in Conte's first campaign.
"Last season it was more easy to play every game every week. We were more fresh," Hazard said. "Now it's different, but we need to adapt to the situation.
"We will give everything, but I think we're on the same level as last year.
"The difference between this year and last year is Manchester City and United are stronger. We are ready, we know the Premier League is long, so we have time to come back."
