Hiddink admits Chelsea must buy 'firepower'

Chelsea boss Guus Hiddink admits they need to sign a new striker in January.

Radamel Falcao has suffered an injury which will keep him out until February and Loic Remy is also unavailable.

Diego Costa has been out of form scoring just six goals in 22 appearances this season.

Hiddink said: "If it's a long period of instability, then yes we might need more firepower."
