Sassuolo suffered a surprise 2-0 friendly defeat to Serie B side Carpi.
This was a local derby in their pre-season training retreat in Carpineti, Reggio Emilia.
Nicola Sansone, Emanuele Terranova, Lorenzo Ariaudo and Domenico Berardi wasted promising opportunities, while Paolo Bianco’s effort was parried.
Carpi broke through at the dawn of the second half, as Jerry Mbakogu intercepted a Francesco Acerbi backpass to beat Alberto Pomini.
Leonardo Pavoletti thought he had drawn Sassuolo level, but was denied by the goalkeeper.
Instead, Mbakogu completed his brace to give Carpi a morale-boosting win.
