Earlier this season, Besiktas announced that they were in talks to form a partnership with Chelsea, in which the Turkish side would take players on loan from the Blues.
Chelsea have recently been criticised for signing a high amount of young players and loaning them out to feeder club Vitesse Arnhem in the Netherlands - but they look set to do the same.
After Besiktas snapped up Chelsea striker Demba Ba this summer, it seems that relations between the two clubs are at an all time high, and Slaven Bilic's men are looking to take advantage of that.
Besiktas club president Fikret Orman admitted today that the club will sign players in the transfer window amid rumours of a move for Dinamo Zagreb star Marcelo Brozovic, and also admitted that the club are already in talks with Chelsea over a deal - though Petr Cech won't be joining the club.
“We are going to make a few signings during the transfer window,” Orman said. “We will sign a right-back and a centre-back, both will be foreign also we will invest in a young forward."
"We are not interested in Petr Cech but we are working together with Chelsea to sign a player," he added.
Egyptian winger Mohamed Salah would figure to be a sensible target given his lack of first team football at Stamford Bridge, but Orman's comments on the specific positions could open the door for two players.
The first is Danish centre back Andreas Christensen. The 18-year-old defender arrived from Brondby in 2012, and made his Blues debut in the Capital One Cup tie with Shrewsbury Town this season.
Chelsea will no doubt want him to get him some first team football soon, and Orman's admission that the club want to sign a centre back could put him on their radar.
Yet the most likely deal would surely be for Tomas Kalas. The Czech Republic international is currently out on loan at German side Koln, but has barely featured for the Bundesliga outfit, and last week admitted that he may look to leave the club in January.
If that loan deal ends up being cancelled, then a move to Besiktas would be a great chance for Kalas to prove his worth at a good level before returning to Chelsea next summer.
It's bound to be a young player loaned out by Chelsea, but if it helps their relationship with Besiktas then they will no doubt be co-operative with the Turkish outfit.
