Watch as Manuel Lazzari gets a rare goal and Sergej Milinkovic-Savic makes the most of a cheeky set-piece routine, while Sassuolo have scant consolation.
The Aquile broke through with Lazzari intercepting a wayward Gian Marco Ferrari pass to fire in with his weaker left foot.
Davide Frattesi nodded onto the upright and Luis Alberto almost scored directly from the corner flag, but it was the Spaniard’s quickly-taken free kick that sent Milinkovic-Savic clear for 2-0.
Hamed Junior Traore pulled one back for Sassuolo in stoppages.
