Chelsea coach Carlo Ancelotti is happy with the form of Frank Lampard even though he has now failed to score in his last 10 club games.
The England midfielder scored 20 goals last season but has managed just one for the Blues so far this season - in the Community Shield.
Ancelotti said: "I don't know why he is not scoring but I think he is doing a very good job. Against Villa he played very well.
"We had a lot of space to pass the ball through to the strikers and had a lot of chances in the second half.
"I am happy with Lampard's play. I am not interested in the fact that he has not scored. He is working for the team and working very well."
