Watch as Hamed Junior Traore continues his amazing campaign with two splendid goals, in a game where Luis Muriel was on target, while both Sassuolo and Atalanta were denied by great saves.
Maxime Lopez and Mario Pasalic saw their efforts fingertipped out from under the bar, but La Dea were caught out on the counter from the other penalty area, Giorgios Kyriakopoulos setting up Traore to volley off the woodwork.
Traore also struck the upright before completing his brace with a run from midfield.
Gregoire Defrel also went close before a Muriel consolation goal in stoppages.
