Juventus slipped to a disappointing 4-2 defeat at Sassuolo in Serie A on Saturday and their misery was comounded by a calamitous no-look own goal scored by defender Federico Gatti deep in added time.
Not realising that goalkeeper Wojciech Szczesny was way out of his six-yard box, the Italian international intercepted a poor pass from the Pole and sent it into the net without looking.
The former Arsenal shot-stopper was nowhere near getting to the ball and Sassuolo's players celebrated in disbelief as they wrapped up a second win of the season, having lost three of their previous four fixtures in the competition.
Serbian striker Dusan Vlahovic tried to console Gatti as the players walked off the pitch at the end of the match after a defeat which leaves the Bianconeri in fourth with 10 points from their five games.
It was Juventus' first defeat of the season in Serie A. La Vecchia Signora sit two points behind leaders Inter, but will be five adrift if the Nerazzurri beat Empoli on Sunday.
AC Milan are in second place, also with 12 points, one more than surprise package Lecce in third.
Up next for Juve is a game against Lecce on Tuesday.
