Chelsea boss Carlo Ancelotti knows they need to get their title bid back on track against Wolves.
Chelsea have taken just six points from their last six away games in the Premier League.
Ancelotti said: "We have to improve this form. We have not been consistent enough and the gap with Manchester United is down to just one point.
"It is a very competitive championship this year and it seems the teams at home are not so afraid and try to attack us more."
