Borussia Dortmund have extended Gio Reyna's contract until 2025, days after the prodigious American talent turned 18.
It has a good week for Reyna, who scored his first goal for the USMNT in their 6-2 thrashing of Panama, four days on from his senior debut against Wales.
Reyna - who has lined up across Dortmund's final third this season - has contributed two goals and five assists across 12 games in all competitions in 2020/21.
"Gio has developed unbelievably in the past few months," said BVB sporting director Michael Zorc. "He'll definitely be an important part of Borussia Dortmund's sporting future. Personally, I'm very happy that he's decided with full conviction to renew with us for the long term."
The youngest player ever to tally a hat-trick of assists and the youngest American to both play and assist in the UEFA Champions League, Reyna thinks there is more to come from him at the Signal Iduna Park.
Watch: Reyna, like father - and mother - like son
"BVB is a big club that can compete for titles and is represented in all major competitions," he explained. "Young players in particular have the chance to develop themselves here. I've already learned a lot in Dortmund and want to learn a lot in the future too. I'm looking forward to being with BVB in the long term."
Reyna could next be in action for Dortmund as soon as Saturday, when die Schwarzgelben take on Hertha Berlin at the Olympiastadion.
