Chelsea are willing to let their 20-year-old centre back Kurt Zouma join Besiktas on loan in January according to LigTv.
The Black Eagles have been keeping tabs on the 20-year-old as they continue their search for a defender.
Besiktas President Fikret Orman is expected to travel to London this week to meet with Chelsea.
The former AS Saint-Étienne defender has played two games in the Premier League and three games in the UEFA Champions League this season.
Beşiktaş have been in talks with Chelsea over a deal for close co-operation between the first teams, academies, training support and joint scouting projects.
Black Eagles president Fikret Orman confirmed that they were working with Chelsea to sign a player.
“We are working together with Chelsea to sign a player,” Orman said.
Zouma joined Chelsea from Saint-Étienne for £12.85 million last January.
