The manner of Chelsea's 4-0 victory over Wolves is proof they do not need to buy big in January, says manager Carlo Ancelotti.

Michael Essien scored twice inside 10 minutes after Florent Malouda had put the Blues ahead in the fifth minute.

England midfielder Joe Cole completed the rout with his first goal for over a year as Chelsea set a new club record of 12 consecutive home wins.

Victory also strengthened their position at the top of the Barclays Premier League, and Ancelotti was delighted with his side's performance in the light of being without Deco, Frank Lampard, Michael Ballack and Didier Drogba.

Ancelotti claimed that the emergence of youngsters like Gael Kakuta, Fabio Borini and Nemanja Matic could prevent him from having to do any business in the January transfer market.

"This match showed we are in a very good condition because we had a lot of injuries before this game," said Ancelotti.

"But our play was just the same. We put some young players in this team and in January if we maintain this condition, it is not necessary to buy other players.

"They are very good young players and I will use them in the future this season."
