Even as Bianconeri rolled to an ominous 4-0 victory at Ennio Tardini on Saturday, Cristiano Ronaldo and Juventus took out their irritation on Parma.
Juventus were out to make amends on their travels after a midweek draw at home with Atalanta, in which Ronaldo missed a penalty, and did so resoundingly.
Ronaldo scored twice to raise his tally from nine Serie A appearances to a league-high 12, going two ahead of Zlatan Ibrahimovic and Romelu Lukaku.
An opener from Dejan Kulusevski, the winger who dazzled last season on loan with Parma but now belongs to the impressive array of Juve attacking choices, followed his efforts. A late fourth was led by another from that forward line, Alvaro Morata.
