Atalantans 2-1 Juventus will have their hopes of getting a second straight Serie A title boosted after winning at home for the third time in four games.
After missing the previous two games with a calf injury, Marco Vazquez struck the post in the first half and Leonardo Bonucci added the second with a left-foot volley.
Juventus were ahead when Leonardo Bonetti headed in a shot from 25 yards, before Vazqueros side dominated possession and took a third-half lead after only 11 minutes.
However, Atalante equalised for the first time since February when Diego Benaglio headed over from close range.
The win was the Italians’ fourth in a row and is the club’s third win in five games.
They are currently on their way to a ninth-placed finish, a point above second-placed Atalantes and four behind leaders Parma.
