Juventus' unbeaten start to the season came to an end with a 4-2 defeat to Sassuolo after Wojciech Szczesny's mistakes in goal contributed to the team's loss in Serie A on Saturday. The Polish international suffered a shock after 12 minutes when Armand Laurienté's long-range shot struck Szczesny's gloves and ended up in the net. Eight minutes before the end, Szczesny accidentally deflected a shot to Andrea Pinamonti, who headed in Sassuolo's third goal to make it 3-2. The nightmare for Juventus was completed five minutes into stoppage time when defender Federico Gatti, seemingly unaware of Szczesny's advance from his line, accidentally put the ball into his own net.
