Frank Lampard admits Chelsea's midfield is still getting used to manager Carlo Ancelotti's wingless system.
Ancelotti's systems have no use for wingers, so the supply to the strikers comes through the centre and so far this season, apart from the defeat at Wigan, it has worked perfectly.
"You need to mix guile and quality in order to try and penetrate defences through midfield because sometimes without the use of wingers, you need that clever pass through the middle to try and put people through," said Lampard.
"When you have the likes of Didier and Nicolas up front you have to find them and use them and their qualities - that's their pace, their power, their strength and their finishing abilities.
"There's no point playing through midfield all day and keeping the ball. It may look quite pretty but the main idea is to get them in front of goal and I think we've done that so far."
