Guus Hiddink wants to bolster his strike force in January and has made the AC Milan forward and Colombia international his No.1 target for the transfer window
Chelsea are set to make a £30 million bid for Carlos Bacca in January, according to Spanish publication Estadio Deportivo.
Hiddink is concerned over a lack of attacking options at the club, with Falcao set to return to Monaco and Loic Remy linked with a move to Aston Villa.
Colombia international Bacca, who moved to AC Milan from Sevilla in July 2015, has emerged as Hiddink's No.1 transfer target.
Bacca has scored eight goals for Milan and would offer competition for Diego Costa, who is returning to form under Hiddink.
