Chief executive Peter Kenyon believes Chelsea will not need to buy players in January in order to strengthen their squad.

Kenyon is convinced the return of the Blues' injured players which include Ricardo Carvalho, Michael Essien and Juliano Belletti, in addition to the regular participation of Didier Drogba, will prove sufficient to boost the London side.

"I don't think we will be doing any business in the January transfer window because the type of players we are looking for are not available," said Kenyon at a press conference to announce a four-year sponsorship extension with tour operator and travel partners Thomas Cook.

"Another reason is that we have still got some long-term injuries coming back and in January or February, Chelsea will have more player availability.

"We put our squad together in the summer and we are concentrating on the squad we have and making sure our players get back from injury. On that basis, we think we have got a good enough squad to improve on last season."
