Juventus have equalled the best ever start after 15 games of a season in Europe's top-five leagues following a narrow Derby d'Italia defeat of Inter.
Mario Mandzukic's second-half header earned a 1-0 home win against the Nerazzurri on Friday, moving Juve 11 points clear of Napoli as they seek an eighth straight Serie A title.
And having collected 43 points from their opening 15 games, Juve levelled the record set by Ligue 1 champions Paris Saint-Germain earlier this month.
PSG won their first 14 league games under new coach Thomas Tuchel before dropping points for the first time in a 2-2 draw at Bordeaux on Sunday.
Juventus' record has been pristine since Genoa were able to claim a 1-1 draw at Allianz Stadium on October 20 and they have kept five clean sheets in a row in all competitions.
Both teams are on track to defend the titles they won easily last year, with European success a target for PSG and Juve after their continued domestic dominance is confirmed.
