Simone Inzaghi’s team will now face Napoli on Monday night at the same stadium after the Italian champions beat Fiorentina 3-0 on Thursday.
Inter have a tight title race with Juventus and the Champions League last 16 to contend with in the coming weeks but Inzaghi brought out the big guns to shoot down Lazio.

This season’s Super Cup in the first to feature four teams, with the top two in last season’s Serie A and the two Italian Cup finalists contesting the tournament.
