Sassuolo completed an extraordinary comeback from 3-1 down to win 4-3 away to Bologna in just 13 minutes, putting them into second place.
The hosts were without Gary Medel, Andreas Skov-Olsen, Andrea Poli and Mitchell Dijks. The Neroverdi were missing Jeremie Boga, Filippo Romagna, Jeremy Toljan, Rogerio and Nicolas Schiappacasse, but a win would put them into second place, leapfrogging Atalanta, Inter and Juventus.
It was Bologna who broke the deadlock with a wonderful sweeping team move played out from the back, finalised by Rodrigo Palacio rolling across a no-look pass for Roberto Soriano to sweep home.
Sassuolo almost equalised 90 seconds later, Lukasz Skorupski rushing off his line to close down Domenico Berardi and Hamed Junior Traore firing the follow-up over the bar.
Berardi did get the equaliser when allowed too much time and space on the edge of the area to pick his spot, curling left-footed into the far bottom corner.
That means Bologna consolidate their all-time Serie A record by conceding for 37 consecutive rounds, just one shy of MSV Duisburg’s European run of 38 set in 1975.
It was predictably wide open between two very attack-minded teams, Palacio’s first touch letting him down when clear on goal, Kyriakopoulos testing Skorupski at the near post and Takehiro Tomiyasu’s volley blocked by Medhi Bourabia on a corner.
Bologna restored their lead with another smart move, Soriano completing a give-and-go with Palacio to thread through for Mattias Svanberg, sweeping into the far bottom corner with the inside of the boot. Sassuolo were furious, as they felt Jerdy Schouten had fouled Djuricic in the build-up, but it was a clean tackle.
On the stroke of half-time, Skorupski got a fingertip to the Ciccio Caputo angled drive, then Djuricic turned over from a promising position.
Andrea Consigli palmed away a Musa Barrow curler and Berardi tested Skorupski at the near post, as it became end-to-end stuff in the second half.
Manuel Locatelli was caught out when trying to dribble his way out of defence, robbed by Riccardo Orsolini who promptly fired in with the aid of a deflection.
However, Sassuolo fought back quickly and got it to 3-2 with Djuricic completing a give and go with Caputo to drill in from the tightest of angles.
Skorupski flapped at a Gian Marco Ferrari effort after a Neroverdi corner and it was a warning for the equaliser, as Palacio’s shinned clearance on another set play accidentally turned into an assist that Caputo nodded in at the back post, anticipating Aaron Hickey.
Sassuolo had the initiative now and wanted all three points, which they nearly got moments later with Skorupski’s reaction save on a Ferrari diving header from close range.
The momentum was clearly with the Neroverdi and they completed the turnaround when Tomiyasu anticipated a low ball rolled across for Caputo, accidentally bundling it over the line from six yards. They went from 3-1 down to 4-3 up in 13 minutes.
It remained wide open, Soriano’s free kick deflected over and Maxime Lopez testing Skorupski. Giacomo Raspadori ran from his own half, dribbled past two players and was pulling the trigger when Ibrahima Mbaye dived in with a decisive last-ditch tackle.
