#1 Kylian Mbappe – (12 goals)
Occupying the number one spot as the most prolific teenager ever to play in the Champions League is Kylian Mbappe. The French youngster has a monstrous goal-scoring record in the competition, having scored 12 times already.
Mbappe netted six times in nine games during his debut campaign in the Champions League, as Monaco reached the semi-final. He then scored four more in eight Champions League appearances last season after joining Paris Saint-Germain from the Principality club.
This season, he has already netted twice in the competition, and he could even extend his goal-scoring record further before December when he will become 20.
And, at this rate, Mbappe should be rivalling the goal records of Cristiano Ronaldo and Lionel Messi by the time he hits his 30s.
