The France youth international, 17, who is represented by Portugal-based sports agency – Epic Sports, has agreed on a pre-contract deal to join the German club in the summer on a free transfer when his contract at PSG expires.
Manchester United, Barcelona, and Juventus were among the clubs willing to sign Coulibaly, but Dortmund moved smartly in the transfer market to land one of the best young talents in Europe for next season.
“It was nice to have so much interest from so many clubs, but I cannot wait to get started with Dortmund,” Coulibaly explained.
“They are a great club with a proven track record of developing some of the best young talents in the world and I aim to do my best for the club and fans.
“I am thankful to my agents [Epic Sports] for helping me in making this move to Dortmund and also to Paris Saint-Germain where I have learnt so much already in my career.”
