Moukoko became the German top flight’s youngest debutant in November, coming off the bench for Erling Haaland against Hertha Berlin aged just 16 years and one day.
The following weeks have seen him also break the records for the youngest Bundesliga start and as the youngest player to feature in the Champions League, beating marks set by Nuri Sahin and Celestine Babayaro respectively.
In six appearances for Dortmund, though, Moukoko, who came to the fore for his prodigious scoring rate at youth level, was still waiting for his first senior goal.
That wait is now over as he provided an instant response for coach-less BVB after they fell behind in the German capital.
The youngster, who started his second consecutive Bundesliga game, was on target on the hour to equalise, just three minutes after Taiwo Awoniyi had fired Union into the lead.
He breaks the record set six months ago by Florian Wirtz, who was 17 years and 34 days old when he netted for Leverkusen towards the end of the 2019-20 season.
Dortmund are keen to get back on track after a rotten run of form which led to coach Lucien Favre losing his job this week, following a 5-1 home drubbing at the hands of Stuttgart.
One of Favre’s biggest legacies at the club was his promotion of young talent, with the likes of Erling Haaland, Jadon Sancho, Gio Reyna and Jude Bellingham all receiving ample chances to shine while teenagers; and now Moukoko is keen to become Dortmund’s latest sensation.
“I can’t do anything about being good at football,” he said in an interview with DAZN. “The one who works harder gets rewarded in the end.
“It was always my dream to become a professional football player. And if you have that dream you have to chase it like a lion.”
