Chelsea managing director Marina Granovskaia is in talks with Napoli defender Kalidou Koulibaly.

Bleacher Report says Granovskaia is in constant contact with Koulibaly's agent over a possible switch.

The latest reports out of Italy suggest Napoli want £63million for the Senegal international.

Manchester City are named as the club in pole position to seal a deal, having already added Nathan Ake this summer.

But the Serie A side may not release Koulibaly unless they are somehow snatch Lille centre-back Gabriel from Arsenal, who is due to have a medical with the Gunners today.
