Milan: High-flying Sassuolo scored three goals in 13 minutes to complete an extraordinary comeback from 3-1 down to win 4-3 at Bologna in Serie A.
The victory saw Sassuolo move second in Serie A, two points below early leader AC Milan.
It was also the third successive match that Sassuolo had scored four goals. Sassuolo, Milan and Juventus are the only teams still unbeaten in Serie A.
It is Sassuolo's eighth season in the Italian top flight and the team has never finished higher than sixth.
In Bologna, Roberto Soriano gave the hosts an early lead but Domenico Berardi curled in an equalizer in the 18th minute.
However, Mattias Svanberg restored Bologna's lead shortly before halftime and, when Riccardo Orsolini's shot was deflected in on the hour, Sassuolo appeared to be heading for its first defeat.
But Francesco Caputo set up Filip Djuricic in the 64th and scored the equalizer himself six minutes later.
The comeback was complete in the 77th when Bologna defender Takehiro Tomiyasu tried to prevent a ball from going through to Caputo and accidentally sent it into the back of his own net.
RAMPANT ROMA
Edin Dzeko scored his first two goals of the season as Roma came from behind to beat Benevento 5-2.
Benevento had won two of its opening three matches but it was still a surprise when it took an early lead through Gianluca Caprari.
But Pedro leveled in the 31st and Roma took the lead four minutes later. Goalkeeper Antonio Mirante gathered the ball and sent a long kick to Henrikh Mkhitaryan who threaded the ball through for Deko to place into the bottom right corner.
Benevento was offered a way back into the game 10 minutes into the second half when Jordan Veretout fouled Artur Ioni?a and the visitors were awarded a penalty. Gianluca Lapadula saw his spot-kick saved but he turned in the rebound.
Roma was awarded a penalty of its own when Benevento goalkeeper Lorenzo Montip tripped Pedro. Veretout converted to make up for his earlier error.
