Szczesny errors, comical own goal sink Juve in loss to Sassuolo
Juventus are two points behind the Milan clubs in fourth after falling to an awful 4-2 defeat at Sassuolo marked by individual errors.
Andrea Pinamonti's third goal in as many games in the 82nd minute, after Wojciech Szczesny patted out Armand Lauriente's shot to the Italy international, and a stoppage time Federico Gatti own goal made sure of the points for Sassuolo just as Juve looked set for a grandstand finish.
"We had our heads in the clouds... we started OK but we had some good opportunities that we didn't take advantage of," said coach Massimiliano Allegri to DAZN.
"They scored with their first attempt on goal and then we lost our heads."
It was a bad day for Poland goalkeeper Szczesny as he was at fault for Lauriente's 12th-minute opener and shown up by a Domenico Berardi strike which restored the hosts' lead four minutes from the break after Matias Vina's own goal put the away side level.
Szczesny also gave Gatti the pass which the young defender inexplicably volleyed back into his own goal.
Berardi was a summer target for Juve but failed to present a bid which could tempt Sassuolo to sell the Italy winger, who crowned his 300th Serie A appearance with his 116th goal in the division.
Pinamonti's strike came four minutes after Federico Chiesa thought he had set up a chance to snatch the points by levelling for Juventus with a deflected strike.
It was Chiesa's fourth goal of the season but instead of pushing Juve on to the win Massimiliano Allegri's team collapsed to a poor loss.
