STAM A MAJOR DOUBT FOR LAZIO
The former Manchester United man has suffered a recurrence of an injury to his right foot and is not expected to play on Wednesday.
Stam was substituted at half-time for Giuseppe Favalli, but not before picking up a booking in what was only his third appearance for the Biancoceleste.
Lazio have suffered from a less than impressive start to the season with only one victory - a 2-1 win against Copenhagen in the Champions League qualifying round.
Draws in the opening three Serie A games have brought only one goal for Dino Zoff's side, although defensively they have been solid.
A loss at the hands of Galatasaray on Tuesday has put pressure on Zoff to start producing - with creativity desperately needed, despite the summer signing of Gaizka Mendieta.
