Cristiano Ronaldo shrugged off the disappointment of his midweek sending off to score a late goal as Juventus preserved its perfect Serie A start on Sunday.
Ronaldo pounced nine minutes from time to set Juventus on its way to a 2-0 win at newly promoted Frosinone, which has still to score a goal this season.
It was Ronaldo's third goal in two Italian league games after the Portugal star took a while to get off the mark for his new club following his move from Real Madrid.
Ronaldo had been sent off in Juventus' 2-0 win at Valencia in the Champions League on Wednesday after appearing to pull at an opponent's hair.
"No one expected anything different from Cristiano, he will score so many goals and he is the least of our problems," Juventus captain Giorgio Chiellini said.
"He was unlucky Wednesday but he will always be decisive in our matches."
Ronaldo came close to scoring early on against newly promoted Frosinone but was denied by a goal-line clearance from Marco Capuano.
Juventus struggled to break Frosinone down but, just as it looked as though their 100 percent record this season was set to end, Miralem Pjanic's scuffed shot ricocheted into Ronaldo's path and he swept it home.
Ronaldo also sparked the counterattack in the dying moments of the match which led to Juventus' second goal by Federico Bernardeschi.
