Daily Bild claims that the Serie A giants are weighing a €20M bid for the Croatia international after the Euro 2008 finals.

On the other hand, it is believed that the 27-year-old forward is ready to leave the Black Yellows should a big offer arrives for him.

Petric has 12 Bundesliga goals so far this season, only four behind Bayern Munich's unstoppable goal machine Luca Toni.
