Napoli, Milan and Sampdoria all maintained their winning start to the new Serie A season, while newcomers SPAL were also victorious in Sunday's action.
Title contenders Napoli had to come from behind to make it two wins from two as they beat Atalanta 3-1 at Stadio San Paolo.
La Dea took a surprise 15th-minute lead through Bryan Cristante and held on until after the break when Piotr Zielinski restored parity in the 56th minute before further goals from Dries Mertens (61') and Marko Rog (87') sealed the comeback for the third-placed Azzurri.
Meanwhile, Milan also kept up their 100% record in the league with a 2-1 triumph over Cagliari at the San Siro to occupy fourth position, behind leaders Juventus, Inter Milan and Napoli.
The Rossoneri got off to a flying start when Patrick Cutrone opened the scoring in the 10th minute, but they were eventually pegged back by Joao Pedro's 56th-minute equaliser.

However, Suso restored their lead 14 minutes later and Vincenzo Montella's title hopefuls held on for their second victory on the spin.
Sampdoria themselves have made an impressive start to proceedings after recording a 2-1 win over Fiorentina at Stadio Artemio Franchi to heap more pressure on the hosts.
La Viola had lost their top-flight opener to Inter and were trailing 2-0 at half-time in Florence following quick-fire goals from Gianluca Caprari (32') and Fabio Quagliarella (35' pen).

Milan Badelj managed to halve the deficit five minutes after the break, but La Samp saw out the remainder of the second half to clinch their second consecutive three-point haul to sit fifth in the standings.
Elsewhere, newly-promoted SPAL remain unbeaten after they claimed a dramatic 3-2 victory over Udinese at Stadio Renato Dall'Ara.
Spallini almost let slip a two-goal lead having gone ahead through Marco Borriello in the 25th minute before Manuel Lazzari doubled their advantage eight minutes into the second half.
Bram Nuytinck (72') pulled one back for the visitors to give them hope and a penalty from Cyril Thereau three minutes from looked to have secured a share of the spoils, but Luca Rizzo popped up in the fourth minute of stoppage time to score the winner for the hosts.
Torino claimed their first victory of the new campaign after seeing off Sassuolo 3-0 at Stadio Olimpico Grande Torino.
Andrea Belotti (44') gave Toro the lead just before half-time, before late strikes from Adam Ljajic (84') and Joel Obi (88') sealed the win.
Lazio needed a late winner to maintain their undefeated start in 2017/18 as they edged out Chievo 2-1 at Stadio Marc'Antonio Bentegodi.
The two teams went into the break at level pegging after Manuel Pucciarelli (34') had cancelled out Ciro Immobile's 11th-minute opener for the visitors, but Simone Inzaghi's side came away with all three points when Sergej Milinkovic-Savic struck in the final minute.
