Interim Chelsea manager Rafael Benitez has hinted he could dip into the transfer market in January as he looks to bring in reinforcements.
The Blues will be left short of options in January with John Obi Mikel heading to the African Nations Cup and Oriol Romeu ruled out for the rest of the season with cruciate knee ligament damage.
With Michael Essien on loan at Real Madrid, Ramires is the only holding midfielder available to Benitez and the boss has set his sights on bringing in cover.
"You need to know the players and find the balance," Benitez said in The Times. "If you have too many players with quality - these players we were talking about, all dynamic but cannot regain the ball - you do not have the balance. If you give the ball away, you have to regain [it]."
Chelsea have been linked with Corinthians' Paulinho, Newcastle's Cheick Tiote and Everton's Marouane Fellaini, while they have been tipped to make a move for Atletico Madrid's Radamel Falcao.
"The club is working and always looking for good players, so we'll see if there are any surprises," Benitez said in Japan ahead of Thursday's Club World Cup semi-final against Monterrey.
