Chelsea boss Rafa Benitez expects to buy this month.
With Victor Moses and John Obi Mikel due to depart for African Nations Cup duty following the QPR game, Benitez admits he needs to bring players in during January.
"You can always improve things, especially when you have injuries, and we lose two players to the African Nations Cup," the Spaniard said.
"Obviously we need bodies but I am really pleased with the squad, they train well, the commitment is there and they are keen to learn.
"I think we will do our job (in the window) and hopefully it will be a good job."
