The reigning champions are now only one point behind Napoli and moved a point clear of city rivals AC Milan into second place. Domenico Berardi gave home side Sassuolo the lead from the penalty spot midway through the first half as Inter faced the prospect of slipping seven points behind Napoli this weekend.
But the game changed when Inter boss Simone Inzaghi made a quadruple change in the 57th minute, including bringing on Dzeko. The Bosnian striker netted just a minute later, meeting Ivan Perisic's cross with a diving header at the back post.That goal took the veteran level with Ciro Immobile at the top of the league's scoring charts on six, but he was not done there.
