Jurgen Klinsmann's son Jonathan has been invited to a Germany goalkeeper camp, setting up a potential battle with the United States for his international registration.
The U.S. under-20 international holds both German and American citizenship, but has yet to receive a senior call up to either national side.
"It's an honour for him," ex-USMNT coach Klinsmann said.
"We will discuss this issue and make a decision should this moment come. If his development continues like that, he must not hide from anyone of his age group."
Having joined Hertha Berlin in 2017, Klinsmann has struggled for first team action and has largely featured for the club's U23 side in the regional fourth division.
But after initial problems settling in, he has progressed and the invitation to the DFB keeper camp marks the first time the 21-year-old has been recognised as a potential future option for Germany.
"Jonathan made a giant leap in his first year as a pro at Hertha BSC," Klinsmann, a 1990 World Cup winner and 1996 European Champion with Germany, added.
"He gets more consistent and confident with every week."
Klinsmann has represented the United States at U18 and U20 level but would be eligible to represent the Nationalmannschaft if he gets a senior call up, as he has yet to receive one with the USMNT.
Last year, 24 keepers born between 1997 and 2003 were invited to take part in Germany's annual keeper training camp in Kaiserau, near Dortmund.
