The Nike International Friendlies, the U-17s' biggest event outside the Concacaf U-17 Championship and the U-17 World Cup, date back to 2001 provided a stage for future U.S. full national team players such as Christian Pulisic, Kellyn Acosta, Tyler Adams and Josh Sargent -- as well as Brazil's Phillipe Coutinho, Neymar and Marcelo, and England's Jadon Sancho.
"The reality of the national team is that the player pool is constantly being evaluated," said Tsakiris. "High-level games like these provide an invaluable opportunity to see the progress of our players and for them to show us that they deserve to be a part of our group moving forward."
The U.S. U-17s started their run toward next spring's Concacaf 2019 U-17 World Cup qualifying tournament a year ago.
• Earning first U-17 callus are Masango Akale, Trace Alphin, Andre Luiz Costa, Cameron Dunbar, Sebastian Falsone, Jonathan Gomez, Ruben Hernandez and Alex Villanueva. The Brazilian-born Costa plays in Spain, while Hernandez is at Leon in Mexico.
• MLS players George Bello (Atlanta United) and Gianluca Busio (Sporting KC) are unavailable because their teams are still alive in the conference finals. Both have dressed in the playoffs.
