Manchester United are being linked with Borussia Dortmund defender Neven Subotic.
Subotic has been a long-term target for United manager Sir Alex Ferguson, who has pumped skipper Nemanja Vidic for information on his Serbia teammate.
Italian media sources say United are lining up a €20 million bid for Subotic.
Interestingly, United chief scout Martin Ferguson was in Italy last week to see Udinese centre-half Mehdi Benatia in action.
