Paulo Dybala and Cristiano Ronaldo have netted and goalkeeper Gianluigi Buffon set the Serie A appearance record in Juventus' 4-1 defeat of Torino, which put the leaders seven points clear of Lazio before their late game with AC Milan.
Dybala opened the scoring on three minutes on Saturday, storming in the box and finding the net as Armando Izzo deflected his shot.
He and Ronaldo have struck in all of the four games played since the league recommenced after the coronavirus lockdown.
Dybala had also scored in the last league game before Serie A was suspended in early March and was one of 23 top-flight footballers in Italy who suffered contagion.
Juan Cuadrado then fired firmly into the far corner as Ronaldo fed him on the right 29 minutes into the Turin derby, which opened matchday 30 at Juve's Allianz Stadium.
Three minutes later, the 42-year-old Buffon bravely saved a Simone Verdi drive in his 648th record league appearance, but was beaten by an Andrea Belotti penalty awarded in stoppage time after video review decided Matthijs de Ligt had handled.
Ronaldo drilled home his first free-kick in two Juve seasons on 61 minutes and is now on 25 goals, four behind Lazio top scorer Ciro Immobile.
"We knew it was a hard game, but we played well and put pressure on Lazio," Ronaldo said.
"I needed a free-kick goal to gain confidence. It is important to win, regardless of who scores the goals."
Il Toro's third straight defeat got worse after a late own goal from substitute Koffi Djidji and they sit six points clear of the three-team relegation zone with eight games to go.
Relegation remains a big threat for third-last Lecce after a 4-2 loss at Sassuolo, who moved into ninth place.
