Chelsea No2 Roberto di Matteo says they're confident of closing a deal for Bolton Wanderers defender Gary Cahill.

Di Matteo is keen for Chelsea to finalise the deal for Cahill but he does not expect the club to recruit any more players during the transfer window.

"A fee has been agreed and there are on-going negotiations for personal terms," Di Matteo said.

"He has developed into a top central defender in the Premier League. He has made selection for the England team, he's a very good age.

"He would add very good qualities to our squad.

"I wouldn't expect too much to happen in this market. We are happy with the quality we have. We are very happy with the team, with the players we have."
