The 25-year-old defender headed home from a cross from Andrea Cambiaso shortly after the start of the second half. For Gatti it was already his third competition goal. Victor Osimhen’s 1-1, after a mistake by Juventus keeper Wojciech Szczesny, was canceled for offside.
After the victory, Juventus has 36 points from fourteen games and has one point more than Internazionale. The Milan team will play against Udinese on Saturday evening (8.45 pm) in San Siro. Earlier on Saturday (6 p.m.), number eight Atalanta will face number three AC Milan in Bergamo.
Napoli, which won the Serie A title last season, is in fifth position and can be passed by Fiorentina and Bologna on Sunday.
