Barca's move for Bayern Munich fullback Philip Lahm this week has fueled speculation that Zambrotta could be made available at the end of this season.

Controcampo says Milan management are still not entirely satisfied with their options at left-back and would jump at the chance of taking Zambrotta to the San Siro. A return to Juve, meanwhile, could also be on, particularly after the way the board were able to secure Alessandro del Piero to a new contract this week.
