Chelsea manager Guus Hiddink has no idea when striker Radamel Falcao will be available for selection again as he continues to recover from injury. The Colombia international has not played since October after suffering an "important injury" while he has also been linked with a move back to Monaco midway through his season-long loan spell at Stamford Bridge.

The 29-year-old has scored just one goal in 12 appearances for the Blues in all competitions but with the player currently out injured Monaco vice-president Vadim Vasilyev says he will not be returning to the principality. Diego Costa and Loic Remy have been in and out of the first team due to their own fitness concerns but the continued absence of Falcao remains a concern for Hiddink.

Falcao has been beset by injury problems since suffering a knee injury in January 2014 which saw him miss the subsequent World Cup and led to an unsuccessful spell at Manchester United. Nevertheless, with Chelsea fighting on three fronts Hiddink has missed him.

"He's just with the physios working," Hiddink said ahead of West Bromwich Albion's visit, according to ESPN. "What he's doing is purely medical. He's not on the [training] pitch, he's completely in the doctors' and physios' hands. When he's declared fit it will take time to get him game fit, so it will last days or weeks. I don't know [when he will be back]."

Diego Costa and Oscar are both available to Hiddink for the visit of West Brom, despite the pair going off during Chelsea's FA Cup third round win over Scunthorpe United. Costa limped off late on due to a knee problem while a toe injury forced Oscar to be substituted at half-time in the 2-0 win.

Loic Remy is also an option for Chelsea after a calf problem in a further boost for Hiddink, who is looking to claim a third win in a row as interim coach. He wants the ex-Queens Park Rangers forward to step up in the coming weeks having rediscovered full fitness and has no plans to allow him to leave in the January transfer window.

"With this multitude of games [over the festive period] I hope Remy picks it up," he added. "Although he was only in training this week I hope he will deliver if he is needed. We have Costa and him, so I hope they stay fit. That's why I hope he can make his next step and get even more fit. At this moment, no [he will not be leaving in January]. He will stay until the end of the season."
