On 18 August, Ronaldo made his debut in a 3–2 away win against ChievoVerona. On 16 September, Ronaldo scored his first two goals for Juventus in his fourth appearance in a 2–1 home win over Sassuolo in Serie A; his second was the 400th league goal of his career. On 19 September, in his first Champions League match for Juventus, he was sent off in the 29th minute for "violent conduct", his first red card in 154 tournament appearances. Ronaldo became the first player in history to win 100 Champions League matches, setting up Mario Mandžukić's winner in a 1–0 home win over Valencia, which sealed Juventus's passage to the knock-out stages of the competition. In December, he scored his tenth league goal of the season, from the penalty spot, netting the final goal in a 3–0 away win over Fiorentina. After placing second in both the 2017 UEFA Men's Player of the Year and 2017 The Best FIFA Men's Player for the first time in three years, behind Luka Modrić, Ronaldo performances in 2018 also saw him voted runner-up for the 2018 Ballon d'Or, finishing once again behind his former Real Madrid teammate. Ronaldo won his first trophy with the club on 16 January 2019, the 2018 Supercoppa Italiana, after he scored the only goal from a header against AC Milan.
