On 12 February, Buffon kept his 50th Champions League clean sheet in a 2–0 away win over Manchester United, becoming only the third goalkeeper to reach this milestone after Iker Casillas (57) and Edwin van der Sar (51). He also made his 121st Champions League appearance – excluding qualifying rounds – during the same match, which made him the player with the tenth-most appearances of all time in the competition. In the return leg in Paris on 6 March, Buffon came under criticism in the media for committing an error with the score tied 1–1, after he spilled Marcus Rashford's long-range shot, thus allowing Romelu Lukaku to score from the rebound and send United into the lead; following an injury-time goal from a penalty by Rashford, Manchester United completed a comeback to win the match 3–1, advancing to the Champions League quarter-finals on away goals. PSG finished the season as Ligue 1 champions, which saw Buffon win his tenth league title of his career, the most of any Italian player. PSG later lost 6–5 on penalties to Rennes in the 2019 Coupe de France Final, following a 2–2 draw after extra time, although Buffon did not appear during the final.
