Home » Unlabelled » Sassuolo 3-1 Inter: Mancini's men slump to second successive league loss
The Nerazurri had won all three previous meetings between the two sides and scored 15 goals without reply, but that all changed at the Stadio Citta del Tricolore with a comfortable home win piling the pressure on Mancini.
Simone Zaza broke the deadlock with a powerful effort from 18 yards, with Nicola Sansone - who, along with Isaac Donkor, was later sent off - extending the hosts' advantage before half-time.
Xherdan Shaqiri led Inter's charge after the break, but was denied a first Serie A goal for the club when a low shot struck the foot of Andrea Consigli's post.
The introduction of top scorer Mauro Icardi gave Inter late hope with an 83rd-minute strike, but - following a red for Sansone - Donkor was given his marching orders in conceding a penalty that Domenico Berardi converted.
Victory moves Sassuolo above their opponents in the league, Eusebio Di Francesco's side climbing into eighth, while Inter fall to 12th.
