Werder Bremen will sign U.S. under-20 international attacker Josh Sargent when he turns 18 in February.
Sargent, 17, featured for United States at the under-20 World Cup in South Korea, where he scored four goals.
He has already trained with several European clubs including PSV Eindhoven and Schalke but has made the decision to join Bremen.
"We've tracked Joshua for a long time, and therefore it wasn't a big surprise to us that he made himself known internationally through remarkable performances," Bremen squad manager Tim Steidten said of the Scott Gallagher Missouri player.
"He's among the most promising players of his age group worldwide."
Sargent will join the U.S. U17 team at the World Cup in India in October, and is expected to arrive at Bremen ahead of his 18th birthday on Feb. 20.
"Josh can get to know the club and the city. He will train with our U23 team, and play matches from the summer on," Steidten said.
Sargent said: "I am already looking forward to the coming year and the new sporting challenge at Bremen.
"They made great efforts to get me, and in the past have shown they can help young talents like me to an ideal start to their professional career.
"Therefore, the decision to continue my career in Bremen was not difficult."
