Juventus drew level on points with Serie A leaders Napoli after a hard-fought 1-0 win over a 10-man Lazio side in Turin on Saturday. Meanwhile, AC Milan showed resilience, securing a 1-0 victory against Udinese despite playing for over an hour with a man down.
Mario Gila's own goal five minutes from time gave Juventus the breakthrough, dealing a crushing blow to Lazio, who had fought valiantly after losing Alessio Romagnoli to a straight red card in the 24th minute.
Juventus manager Thiago Motta's side looked poised to dominate following Romagnoli's dismissal for a foul on Pierre Kalulu, who was through on goal. However, the Bianconeri struggled to break down Lazios resilient defence and only secured victory when Gila inadvertently diverted Juan Cabals low cross into his own net.
Despite their defeat, Lazio, who remain in fifth place, were left frustrated by the officials. They claimed Douglas Luiz should have been sent off for a punch on Patric, which VAR officials did not penalise.
Although Juventus are level on points with Napoli and boast a superior goal difference, they remain behind Antonio Conte's side, having played an extra match. Napoli can reclaim sole possession of top spot with a win against Empoli in Sunday's early kick-off, while champions Inter Milan, tied with local rivals AC Milan, face Roma later in the day.
