Tuchel's first match in charge also yielded his first honor at the club, as PSG defeated Monaco 4–0 to win the Trophée des Champions on 4 August. He also saw victory in his first league game, as the club defeated Caen 3–0 eight days later. After enjoying a brief unbeaten record, Tuchel suffered his first defeat at PSG on September 18, losing 3–2 away to Liverpool in a UEFA Champions League group game. However, by November, Tuchel would break the record for the most wins to start to a domestic league season, as he registered twelve straight victories. The record was later extended to include two additional victories, prior to the club ending its 100% start to the season on 2 December, after PSG drew 2–2 away to Bordeaux. Tuchel then guided Paris Saint-Germain to top spot in the club's Champions League group, with a 4–1 win over Red Star Belgrade on 12 December. By securing victory over Nantes on 22 December, Tuchel also broke the record for most points by Christmas in Ligue 1, with 47 after 17 games eclipsing the record of 45 after 17 set by PSG in the 2015–16 season.
