Borussia Dortmund's 15-year-old wonderkid who already trains with the first team

Youssoufa Moukoko is already making his mark on German football.

The 15-year-old is the latest prospect to come through the ranks at Borussia Dortmund and has been training with the first team since January.

Since his breakthrough into the first team at Dortmund, the German Football League (DFL) have been forced to change their regulations.

Before Moukoko, players couldn't make their first team debuts in the Bundesliga until the age of 16 years and six months.

However, that minimum age has been brought back to just 16 years old in a move dubbed as the 'Moukoko law'.

Nuri Sahin currently holds the record for the youngest debutant in the Bundesliga, playing for Dortmund at the age of 16 years, 11 months and one day.

"He has what it takes to reach the highest level," Dortmund youth coordinator, Lars Ricken, told Kicker about Moukoko.

The Cameroonian-born teenager has been training with the first team in pre-season, but the idea is for him to stay with the Under-19s in the upcoming season.

While playing for the U17s, Moukoko scored a record 90 goals in 56 games, before following that up with 34 goals in his first 20 games for the U19s.

At the age of 12, he'd already made his debut for Dortmund's U17s and Germany's U16s.

"He's an outstanding talent and we want him to learn how to train and play with adults," said Michael Zorc, BVB's sporting director, last November.

Dortmund's first team already boasts talent like Erling Haaland, Jadon Sancho, Giovanni Reyna and Jude Bellingham.
