Interim Chelsea manager Guus Hiddink has reportedly been told he must sell Loic Remy before he can bring another striker to Stamford Bridge.
The Daily Star is reporting Blues owner Roman Abramovich has refused to fork out for another forward until Remy is no longer on Chelsea's books.
Hiddink is reportedly looking to strengthen his strike force with Colombian ace Radamel Falcao continuing to be plagued by injury.
Corinthians striker Alexandre Pato is the latest player to be linked with a move to the London club, while Atletico Madrid pair Antoine Griezmann and Jackson Martinez, Leicester City's Jamie Vardy and West Bromwich Albion's Saido Berahino have also been mooted as possible recruitment targets.
