Champions League qualification from their group could propel the Italian side to make a move for the highly-rated Serbia central defender, reportedly chased by several sides. Napoli are the latest in a long list of clubs to be linked with Borussia Dortmund defender Neven Subotic.According to Itasportpress.it, the 22-year-old Serbia international, who was dropped but later defended by coach Jurgen Klopp following their 4-0 Bundesliga win over Augsburg, is wanted in Italy.Last month Subotic said he was happy in Dortmund, and made clear he would only leave for a top European side.Chelsea, Roma, Juventus and AC Milan have all been linked with the stopper.But, if reports are to be believed, Napoli have joined the race to sign him in January.Club president Aurelio De Laurentiis will dig deep to strengthen, especially if Napoli get through their Champions League group, which they are contesting with Manchester City, Bayern Munich and Villarreal.However, Dortmund are said to be looking for at least €20 million for their man if he becomes available for sale.Subotic joined the Bundesliga champions from Mainz in 2008 and he has a contract there until 2014.?
