Hazard said: "Chelsea are expected to win all the time - nothing has changed in that regard. I think the fact we are playing better is down to the psychological effect of having a new manager.
"I want to win two trophies with Chelsea this season, ideally the Premier League title and the Europa League. Our results so far this season have been 50-50. We started well but then went through a slump that led to the change of manager.
"The biggest disappointment has been going out of the Champions League, even though we still have the Europa League. We still have four targets - there are the two domestic cups and the Europa League. We are Chelsea, so we have to beat Sparta Prague when we meet next month.
"And despite everything, there is the league title. Although there is a gap between us and the top, we have a game in hand and there are 18 matches left for us to play.
"United had a big lead last season as well and ended up being overtaken by Manchester City."
