Besiktas are said to be in formal negotiations with Chelsea over the signing of Filip Jorgensen. The goalkeeper has been a target for some time, and talks are said to be intensifying as the window progresses. The player remains under contract, but movement looks increasingly likely the longer talks go on. The transfer remains in progress, and with no other clubs involved, Besiktas look to be negotiating from a comfortable position. Defensively, Besiktas are sitting around the league average this season, at 1.29 goals conceded per game. Someone like Filip Jorgensen could keep them steady but also raise the level when it matters most. Alongside this, Chelsea are said to be exploring Sandro Tonali, Othmane Maamma and Ethan Nwaneri with Besiktas likewise connected to Antonin Kinsky and Kobbie Mainoo.
