Juventus fell to a surprise 3-2 defeat at Sampdoria on Sunday while Internazionale after 13 matches in Serie A after losing against Sassuolo in stoppage time.
Juventus, the defending Serie A champions were resting key players in Andrea Barzagli and Gianluigi Buffon, who were both allowed time to rest from the disappointment of Italy’s failure to qualify for the World Cup on the bench.
The Turin team also had great chances early on with Gonzalo Higuain having a shot deflected wide and Mario Mandzukic and Juan Cuadrado both forcing saves following Higuain passes.
Duvan Zapata, Lucas Torreira and Gian Marco Ferrari put Sampdoria 3-0 up in the second half before Juventus threatened with an astonishing stoppage-time comeback with a penalty from Higuain and a strike from Paulo Dybala.
Zapata’s opener came after a Federico Bernardeschi mistake, with Torreira then firing home their second from 18 yards and Ferrari tapping into an empty net.
Juve, who take on FC Barcelona in the Champions League this week, are now four points behind leaders Napoli, who beat AC Milan 2-1 on Saturday. Inter Milan was able to leapfrog them with a solid 2-0 win over Atalanta later on Sunday.
Sampdoria, meanwhile, moved five points behind Juventus with a game in hand on most other teams.
Inter Captain Mauro Icardi opened the scoring six minutes into the second half at the San Siro when he powerfully met Antonio Candreva’s right-wing free kick.
Icardi went on to claim his 13th goal of the season nine minutes later with another header, stooping to nod Danilo D’Ambrosio’s in-swinging centre into the bottom left corner as Inter made it 13 games without defeat this season.
