Inter will be without goalkeeper Julio Cesar when they face Napoli on Thursday night in Leonardo's first match in charge since he replaced Rafa Benitez.
The Brazil international goalkeeper who missed a sizeable chunk of the first half of the season has suffered a light muscle strain in his left leg.
Wesley Sneijder and Philippe Coutinho will also be unavailable to Leonardo, while Samuel Eto'o is still suspended.
Inter will train at San Siro tomorrow afternoon. The last time they played at home was over a month ago in a 5-2 victory over Parma.
