Moukoko has made the Borussia Dortmund squad for their game against Club Brugge and could make his European debut.
At the weekend he made his Bundesliga debut at the age of 16 years old and one day, becoming the Bundesliga's youngest ever player.
If he plays at Signal Iduna Park, he would become the Champions League's youngest ever player, surpassing Céléstine Babayaro of Anderlecht, who debuted at 16 years-old and 87 days in 1994.
However, Borussia Dortmund manager Lucien Favre refused to guarantee that the German will come on: "We will see, we have so many attackers", said the coach.
