Lazio have been struggling with form in the past couple of weeks with 3 consecutive losses. Le Aquile's drop in form has seen them going out of the Europa League as well as out of the top 4 of the Serie A. Lazio defeated Inter Milan in the last round of the Coppa Italia.
One of the in-form teams in Italian football at the moment, the Rossoneri have tasted just one defeat since Christmas. The defeat though came against league leaders Juventus in the Supercoppa Italiana in Saudi Arabia. Gattuso and his men will be looking for another semifinal win against their opponents today after knocking out Lazio in the same round last year.
The recent drop in form for Simone Inzaghi's men can be attributed to their injuries in the defensive department. Luis Felipe, Wallace and Bastos will be missing in action while Senad Lulic is doubtful for the fixture.
Sergei Milinkovic-Savic will be back in action for Lazio.
Giacomo Bonaventura is the only name in the injury list with the midfielder still recovering from injury. Hakan Calhanoglu is also doubtful after the Turkish international is expected to be out due to personal reasons.
Spanish winger Suso will be back in the lineup after missing the last match due to suspension.
