Watford boss Javi Gracia insists Chelsea aren't a one man team.

Belgium international Hazard scored both goals when Maurizio Sarri's Blues won 2-1 at Vicarage Road on Boxing Day.

"I prefer to speak about the whole team. We play against Chelsea - not only Hazard," said Gracia at his pre-match press conference, according to watfordfc.com.

"In the first game he played as a striker and now I think he will play as a number 10.

"We know we have to defend well when he has the ball as he is always able to do something different.

"We always have to have a collective mentality to defend and to attack."
