Arsenal are tracking Napoli defender Nikola Maksimovic ahead of the January transfer window. The 25-year-old was being pursued by Chelsea in the summer but he ended up joining Napoli from Torino after spending the previous season on loan there. However, the Serbian has made just one league appearance this term and he is now considering his options. Arsenal are looking for defensive reinforcements in January and, according to Guerin Sportivo, they could provide Maksimovic with a way out.
