Ansu Fati became, at 17 years and 40 days, the youngest ever goalscorer in the Champions League. He netted the second as Barca won 2-1 at the San Siro against Inter Milan.
The recently nationalised Spaniard scored in the 87th minute, shortly after coming on, with a low drive.
Ansu takes the record from Peter Ofori-Quaye, of Olympiacos, who scored against Rosenborg on October 1, 1997 - at 17 years and 195 days old.
