Tonight he wants to banish his guilt over RDM's axing by putting the Blues on the way to Wembley in their Capital One Cup semi-final first leg against Swansea at Stamford Bridge.
Hazard said: "I feel responsible for Roberto being given the sack.
"He was the manager who brought me to the club and that creates a bond between you. In any case, it is always the players who are to blame when a coach loses his job.
"We are the ones who are out on the pitch, not him.
"Rafa Benitez is a manager who talks a lot with everybody. He doesn't say much to me, as his French is a bit limited, but we can understand each other.
"We expect to play in a more attacking style now, even though we produced some great performances under Roberto, like our 4-2 win at Tottenham."
