Lazio, Inzaghi tries Nani as striker with Immobile not training 48 hours away from the derby

Lazio are showing anxiety as Immobile is not training with 48 hours to go until the derby with Roma. Is it fatigue? Saving energy? Or another injury? It is too early to tell. Regardless, he didn't train with the squad today or did any individual training. A situation to be monitored. Inzaghi? Well he's trying Nani at striker, as Caicedo is out with an injury: Nani "has a lot of quality and experience. He can play as a striker." Lazio's probable formation: Strakosha recovered and will play, Bastos, de Vrij and Radu for the back 3, then Marusic and Lulic. In midfield: Parolo, Lucas Leiva and Milinkovic-Savic, Luis Alberto as trequartista and Nani was tried out as a striker. Immobile didn't train 48 hours removed from the derby which will obviously keep Inzaghi preoccupied.
