Domenico Berardi inflicted the final blow as Milan slipped up 3-1 against Sassuolo at San Siro, suffering back-to-back Serie A defeats for the first time since April.

Alessio Romagnoli's powerful header had been Milan's reward for a strong start, but Gianluca Scamacca's excellent long-range strike and an own goal from the unlucky Simon Kjaer helped mid-table Sassuolo reach the interval with a lead.

Berardi finished off Milan with a fine goal in the 66th minute, the Italy forward showing his class to outwit Romagnoli before beating Mike Maignan.

A red card for captain Romagnoli for hauling down Gregoire Defrel with effectively a rugby tackle compounded a bad day for Milan, who began the day level on points with leaders Napoli.
