Milan new boy Giampaolo Pazzini was forced to watch this morning’s Italy training from the sidelines because of injury.
The striker, who scored a hat-trick for the Diavolo in the 3-1 win at Bologna on Saturday, is struggling with a knee problem.
It is unclear at this stage how serious the issue is ahead of Friday’s game in Bulgaria as qualification for World Cup 2014 begins.
The Azzurri will then face Malta on Tuesday.
Cagliari’s Davide Astori and Roma’s Daniele De Rossi also have fitness issues to contend with.
