Head coach Tab Ramos has named a 20-man squad for the coming tournament in New Zealand, with one spot left to fill.
The British-born defender is eligible for the US through his American father and earned his first call-up to the setup back in August for an Under-18 tournament in the Czech Republic.
After going on to earn a surprise start for the Under-23s during their October trip to Brazil, the emerging centre-back would prove an ever-present for Ramos’ side at the recent CONCACAF Under-20 Championship, where his performances helped them seal a place at this summer's World Cup.
The youngest member of the roster at just 17, he is set to contend with MLS-based pair Erik Palmer-Brown and Matt Miazga for a starting spot, in what looks like one of the strongest Under-20 sides in some time.
"I’m very excited about this particular group,” Ramos told US Soccer. “It was very difficult making the final decision because there were quite a few players who deserved to go to the World Cup. Unfortunately, in the end I can only select a certain number, and I’m very happy with the selections that we made.”
The German-born prospect, who lived in the States from 2006 to 2013 before moving to the Gunners, has been awaiting FIFA’s approval to file his one-time switch, but will need a decision to be made before the official roster deadline on May 15 to make the tournament in New Zealand, which runs from May 30 to June 20.
If clearance does not come in time then the Philadelphia Union’s Zach Pheffer is expected to fill the final spot, having missed out on the initial squad along with other notable omissions like Borussia Dortmund’s Junior Flores, Sunderland’s Lynden Gooch and Columbus Crew SC’s Romain Gall.
The U.S. will kick off the tournament on May 30 against Myanmar, before rounding out the group stage with games against hosts New Zealand and Ukraine on June 2 and 5, respectively.
