Moukolo became the youngest player ever to feature in a Bundesliga match when he appeared off the bench in Dortmund's 5-2 win over Hertha Berlin on Saturday at the age of 16 years and one day.
Born in Cameroon, the teenager has made two appearances for Germany's Under-20 side and turned out for Dortmund's Under-16 outfit at the age of 12.
Haaland, who was the player replaced by Moukolo against Hertha, has said that his teammate is currently "the biggest talent in the world" and "has a big career ahead of him".
"I think he's the biggest talent in the world right now. 16 years and one day, that's quite amazing. He has a big career ahead of him," Haaland told ESPN.
Moukoko has allegedly scored 141 goals in 88 youth appearances for BVB since 2017. body check tags ::
