Borussia Dortmund are preparing to unleash 15-year-old wonderkid Youssoufa Moukoko when the new Bundesliga season begins next month.

Moukoko has taken German football by storm, scoring 128 goals in just 86 appearances for the Dortmund U17s and 19s.

The Cameroon-born Germany youth international has been so impressive, the German Football League changed the minimum age for players to represent their clubs.

Moukoko can now make his Dortmund debut when he turns 16 on November 20. Under previous rules, Moukoko would not have been able to play in the Bundesliga until August next year.

"We are very pleased with this decision," Dortmund academy director Lars Ricken told Kicker. "This could help the clubs but also the young players in their development. A majority of the clubs want to be able to give outstanding talents, on very rare occasions, the chance to take the next step in their development."

The new Bundesliga season will begin on September 18.
