The Independent says sources in Serbia suggested yesterday that the presence of Vidic in the United defence might be an enticement for his compatriot. Ivanovic has also reportedly attracted the interest of Chelsea with his performances for the Russian side Lokomotiv Moscow.
Vidic and Ivanovic have played together in the Serbia national side, though while the Lokomotiv man has played for the full side nine times, he remains a fixture as captain of the Under-21 team.
The player's agent Marco Naletilic indicated that Ivanovic would prefer to play in England, though Internazionale, Milan and Juventus are also interested.
The 23-year-old was outstanding in this summer's Under-21 European Championships in the Netherlands and has indicated that he might be prepared to leave Moscow.
"If I were to leave Lokomotiv, I would want to join one of the biggest sides in Europe – either a team in Italy, England or Spain," Ivanovic said this week.
