Inter pulled one back from the penalty spot seven minutes before halftime when Piotr Zielinski converted after Matteo Tramoni handled inside the box.

Lautaro Martínez nodded in the equalizer two minutes later and Francesco Pio Esposito hit the third on the stroke of halftime when he headed home a cross from Alessandro Bastoni.

Federico Dimarco made it 4-2 eight minutes from time, Ange-Yoan Bonny added a fifth with a nice individual effort four minutes later, and Henrikh Mkhitaryan rounded off the scoring with a sixth in stoppage time.

Inter was six points clear of city rival AC Milan and nine ahead of defending champion Napoli.

The win was especially welcome for Inter given that the top four play each other this weekend. AC Milan is at fourth-placed Roma on Sunday, and fifth-placed Juventus is at home to Napoli on the same day.
