Lazio enter their clash with Leverkusen hoping to keep their good form going. The Italian side won the first leg 1-0, and opened up their Serie A campaign with victory over Bologna. However injuries are a major headache for Stefano Pioli's side. Lucas Biglia is out for a month with a calf injury, while 'keeper Federico Marcxhetti and forwards Filip Djordjevic and Miroslav Klose are also expected to miss the game. However Keita Balde - who scored the winner in the first leg - is fit, and Lazio will hope he can fire again to take them through to the group stage.
