#3 Lionel Messi - 34 years, 167 days (2021)
Lionel Messi has been on a tear for PSG in the Champions League. The seven-time Ballon d'Or winner has netted five times in as many games for his new club since arriving from Barcelona this summer.
His first of two goals against Club Brugge made Messi only the second player ever to score against 38 different opponents in the Champions League.
If the Argentine nets in the knockout round, he'll become PSG's oldest goalscorer in Champions League history. Messi will now hope to replicate his imperious Champions League form in Ligue 1, where he has scored just once in 11 games.
#2 Zlatan Ibrahimovic - 34 years, 167 days (2016)
Zlatan Ibrahimovic is one of the top strikers to have graced the game, especially since the turn of the century.
The AC Milan forward is one of only two players to score over 150 goals for PSG. Twenty of these strikes came in the Champions League. His last strike in the competition was against Manchester City in the 2015-16 quarter-finals.
With Ibra drawing a blank in the return leg, PSG fell to a 1-0 defeat at City to bow out 2-3 on aggregate.
Interestingly, the 40-year-old hasn't scored in the competition in five subsequent games, including four this season with Milan.
#1 Dani Alves - 34 years, 201 days (2017)
Dani Alves is arguably one of the best attacking full-backs in the game's history. The three-time Champions League winner enjoyed a short two-season stint at PSG in the late 2010s. During his first season with them in 2017-18, Alves netted twice in the competition.
His second strike - against Celtic in a 7-1 home win - made the legendary Brazilian full-back the oldest PSG player to score in the Champions League.
Now back at Barcelona, the 38-year-old hasn't featured in the competition since 2018-19.
