16-year-old Youssoufa Moukoko made German football history on Saturday, becoming the youngest Bundesliga player when he arrived in Borussia Dortmund's game at Hertha Berlin.
Moukoko, arriving in the 85th minute, broke the record previously held by Nuri Sahin who was 16 years and 11 months old when he played for Dortmund against Wolfsburg in 2005.
The German side selected Moukoko for their Bundesliga squad this summer but knew they had to wait a few months for the player to be eligible to play for the senior squad. The teenager has been training with the club's senior team since August.

During his time in the Dortmund youth ranks, he scored 127 goals in 84 appearances and managed 26 assists.
Dortmund striker Erling Haaland called Moukoko the best 15-year-old he has ever seen in training in August.
“Moukoko is much better than me at his age,” he told the Bundesliga official website.
“The advantage for him is that he already plays for Dortmund at the age of 15. At his age, I was still playing for my hometown of Bryne. ”
Earlier this year, Dortmund convinced the German soccer league to lower the minimum age in the country's top two divisions from 17 to 16.
The youngster saw a categorical rise in the club's youth ranks following his transfer from FC St. Pauli to Bundesliga 2 in 2016.
Moukoko's development has been so rapid that the German FA decided not to select him for further youth matches until this year earlier, when he made his Under-20 debut in Germany.
“Why should I exclude it now? A lot can change over the next four months, ”German Under-21 coach Stefan Kuntz said last week on whether Moukoko could compete in the European Under-21 Championships.
