Rossi is expected to feature for Italy after catching the eye throughout the Azzurini's European U21 Championship campaign, scoring his maiden international goal against the Czech Republic in his last outing.
All four semi-finalists at the U21 Championship - Holland, Serbia, Belgium and England - are ensured a berth at the 2008 Beijing Olympics. However, England's confirmed absence from next year's Games has opened up a window of opportunity for both Portugal and Italy, who were eliminated at the group stage.
Stuart Pearce's side will not take up their slot in Beijing, as England will instead form part of a Great British side. As such, their berth will be awarded to the winner of Thursday's tie.
