Lazio were trailing to Sassuolo, but eventually the dam broke and they scored six goals to annihilate their opponents.
The Aquile were flying high with four wins, a draw and unlucky defeat to Napoli, despite the injury crisis that continued to rule out Bastos, Felipe Anderson, Wallace and Dusan Basta. Stefan de Vrij, Luis Alberto and Sergej Milinkovic-Savic shrugged off knocks to start. Sassuolo were struggling and had to do without Edoardo Goldaniga, Cristian Dell’Orco and suspended captain Francesco Magnanelli.
Stefano Sensi ballooned over from 12 yards on Pol Lirola’s assist and really should’ve done better. Sassuolo also lost Timo Letschert to a potentially serious knee injury, as he was stretchered off.
Stefan De Vrij was adjudged to have brought down Alessandro Matri, even if he tried to pull out of the challenge, and Domenico Berardi converted to give Sassuolo the surprise lead.
The Neroverdi became very dangerous on the counter-attack, as Thomas Strakosha denied Berardi after the offside trap failed on a Claud Adjapong through ball, then did the same on Alfred Duncan.
Lazio’s first real chance was after 35 minutes, when Ciro Immobile’s header looped just over, but Sassuolo were forced to replace substitute Federico Peluso following a clash of heads.
The Biancocelesti drew level on the stroke of half-time, as Luis Alberto surprised Andrea Consigli at the near top corner, bending his free kick over the wall and under.
Lazio somehow didn’t score on 53 minutes, as first Consigli parried an Adam Marusic strike up into the air, then Francesco Acerbi stopped Immobile nodding in the rebound from a couple of yards.
It turned into a siege and Sassuolo simply collapsed. Luis Alberto curled a corner in for the precise De Vrij header into the far bottom corner from 12 yards.
Moments later, Immobile sprung the offside trap and Consigli ran out to block his path, but Luis Alberto followed it up by dribbling round the ‘keeper to deposit into an empty net.
Claud Adjapong bravely tackled Senad Lulic, but Marco Parolo turned in the rebound for 4-1.
There was only one team in it now and Lazio ran riot with a fifth goal. Consigli did everything he could, beating away both a Lulic strike and the Marusic follow-up, but the third attempt from Parolo was just too much.
Luis Nani made his Lazio debut after the transfer deadline day move, but Luca Mazzitelli slipped and brought down Immobile, the striker converting the penalty for 6-1.
