If you've been impressed by Borussia Dortmund academy graduates like Christian Pulisic and Mario Götze, prepare to be stunned by another outrageously gifted youngster in the BVB stable: Youssoufa Moukoko.
At the age of 12 (do not rub your eyes, yes we did say 12) last October, the striker was the hero of the hour against Schalke, netting a stunning Revierderby brace as the Under-17s recovered a three-goal deficit to draw 4-4, and put his name on the back pages.
The Cameroon-born prospect, now 13, finished the season with 40 goals as Dortmund won the B-Junioren Bundesliga West, with decisive goals from Moukoko in the semi-final against Bayer Leverkusen and final against Bayern Munich.
Watch: Moukoko's wondergoal, scored against Leverkusen!
Moukoko, who was born in Cameroon on 24 November 2004, joined Dortmund from Bundesliga 2 side St. Pauli last year and immediately hit the ground running.
In 2016/17, he was top scorer in the club's all-conquering U-15 side, netting 33 times in 21 games to help them win the Regionalliga West title with five matches to spare. His performances did not go unnoticed by the German FA, who called him up for the U16's 3-1 win over Austria last September.
"It remains to be seen whether or not this will be an extraordinary crop of players," said Peter Wazinski, Moukoko's U-15 coach last term. "But we hope that the majority of them will develop in a similar way to the group born in 1998." That includes current first-team members Pulisic and Jacob Bruun Larsen (on loan at Stuttgart), as well as reserve team players Janni Serra and Dario Scuderi.
While it may be a few more years until Moukoko makes the step up to the pros, there are a number of eye-catching Dortmund teenagers to keep a close eye on in the Bundesliga next season, including Dan-Axel Zagadou and Aleksander Isak, as well as Pulisic.
