Mbappe has broken Lionel Messi's record to become the youngest player to score 15 Champions League goals.
Only just back from injury, the 20-year-old was brought on in the second half of PSG's 5-0 away win against Club Brugge and proved instrumental in securing the comfortable victory as he bagged an impressive hat-trick.
Mbappe's now scored 15 Champions League goals at the age of 20 years and 306 days.
That feat has seen him become the youngest player to bring up the milestone, smashing the record previously held by Messi, who achieved the same aged 21 years and 288 days.
Messi himself had beaten Real Madrid legend Raul's mark of 22 years and 163 days initially, making Mbappe's new record all the more impressive.
The PSG star's hat-trick also made him the first Champions League substitute to score three times since Joseba Llorente did the same for Villarreal in October 2008 against Aalborg.
