Reports suggest that Chelsea will go back in with another offer for Gonzalo Higuain after seeing an initial £50 million bid for the Napoli striker turned down, but is the former Real Madrid man Jose Mourinho's best option?
The Telegraph's Luke Edwards reports that the Blues' boss has been told that the Argentinian hitman is not for sale, however, and that Chelsea should look elsewhere in a bid to solve their striker conundrum.
So far this season, Fernando Torres, Samuel Eto'o and Demba Ba have been far from their reliable bests, leading the west London club to seek attacking reinforcements, but January will be a tough time of year to sign the cream of the crop.
Nonetheless, there are assets out there that Mourinho can still hold a hope of luring to Stamford Bridge, some possessing more value in their signature than others.
All statistics are provided by Transfermarkt.co.uk.
Lazar Markovic has an odd and rather unique history with Chelsea in that the Premier League giants were reported to have already signed for the Blues over the summer, only for it to turn out that he was instead heading to Benfica.
According to a report from Sky Sports' Jure Bohoric back in June, Partizan Belgrade had stated that the attacker was on his way to the English top flight, but it was not to be.
101 Great Goals have even gone as far as to report that the Blues have once again sealed a deal for the starlet, per Portuguese outlet O Jogo:
Regardless, Benfica's financial problems could mean that Chelsea get their man regardless this winter, and although he's played primarily out wide of late, the Serbian youngster could still be a highly valuable pickup.
John Cross of the Mirror has claimed that the Portuguese powerhouse has placed a £12 million price-tag on the 19-year-old, which is well within the Blues' funding.
The teenager hasn't been the same prolific asset at Benfica, scoring just three goals in eight league starts, but his development can easily get back on track at Stamford Bridge given that the forward isn't yet out of his teens.
Manchester United's ongoing slip down the Premier League rankings has created some unrest among the Old Trafford camp, and it will be like music to Chelsea's ears to hear that Wayne Rooney is uncertain about his future at the club.
The Metro's Jamie Sanderson has reported that the Red Devils' forward could leave his current surroundings should he feel things are going too far south with United; however, the Blues may look to strike a deal sooner.
Rooney has scored 11 goals and made 19 assists across all competitions so far this season and has been one of the few beacons of light in David Moyes' squad, only increasing his stature in Mourinho's vision.
With less than 18 months left on his current deal, it's a situation that needs fine balancing from United, who won't want to lose their attacking talisman, but will have a constant eye on the possibility of losing his services on a free transfer.
Thanks to his scoring exploits in the Spanish top flight this term, Diego Costa is one striking power showing as much reliability going forward as all three of Chelsea's main attacking outlets combined.
The Brazilian has scored 19 league goals this season, deservedly earning the attention of many a European titan, a contingent among which Mourinho's side supposedly number.
The Daily Star's David Woods has claimed that the Blues are keen to offer the £32 million necessary to trigger the forward's release clause in January.
In the absence of Radamel Falcao, Costa has gained some valuable experience leading Atletico Madrid's attack almost single-handedly this term, and would undoubtedly fit the tactics that Mourinho has looked to employ.
