Jadon Sancho became the youngest Englishman to score in the Bundesliga after opening his top-flight account in Borussia Dortmund's 4-0 drubbing of top-four rivals Bayer Leverkusen on Saturday.
Sancho broke the deadlock in the 13th minute at the Signal Iduna Park, curling low into the bottom corner after being played clean through by USA international Christian Pulisic.
"When I missed my first chance, I was upset with myself because it was 0-0," Sancho told bundesliga.com, having shot straight at Leverkusen goalkeeper Ramazan Özcan with the first meaningful opportunity of the game.

"But I made sure I scored with the second chance. I'm really happy I scored my debut goal.
"It's been hard getting back into the team, getting my fitness, but now I feel good."
The Londoner, who joined Dortmund from Manchester City in summer 2017, was making his ninth Bundesliga appearance and his fourth start.
