UPDATE: Alejandro Bedoya withdrew after being injured in his MLS game on Saturday.
1. The search for a successor in goal begins.
Klinsmann will test David Bingham, Ethan Horvath and William Yarbrough -- three caps among them -- in the two friendlies.
"I think the goalkeeper position is unique," he said. "Obviously we have the two experienced guys with Tim Howard and Brad Guzan. Both are in different situations right now -- Tim is obviously very busy with the Colorado Rapids and Brad is not getting the opportunity to play at Middlesbrough. I think it's a perfect time to give an open window to three younger goalkeepers with William Yarbrough, Ethan Horvath and David Bingham. That's why we decided to leave the two older guys out and give these three youngsters a chance to prove their point. That kind of opportunity is very rare."
2. Another chance for German-Americans.
Klinsmann recalled Timmy Chandler, Julian Green and Danny Williams, bringing to five the number of German-Americans currently in the team.
Chandler and Green went to 2014 World Cup, while Williams had been in the picture for much of Klinsmann's first three years in charge of the national team.
Chandler, who has been starting for Eintracht Frankfurt, was a late scratch for the Copa Centenario. Green has only played three games for the USA since the 2014 World Cup but made the Bayern Munich first team after spending much of the 2015-16 season with its "B" team. Williams has started 10 of 11 games for Reading, currently eighth in the English League Championship.
“For Danny Williams," Klinsmann said in a Q&A released on Sunday, "we recognize his good performances over the last two months with Reading. Now the task is to come in here and show us you’re a difference maker when you get on the field. Timmy Chandler is playing a good role at Frankfurt right now, and he has a similar possibility. Now coming into the national team, they know what that have to do. The national team always has an open-door policy. Young, old, it doesn’t matter. But if you come in and get the opportunity, then you have to grab it. You have to put a stamp on it. That’s what Sacha [Kljestan] did, that’s what [Christian] Pulisic is doing."
3. Gooch gets his call-up.
Born and raised in California to an English father and Irish mother, Lynden Gooch spent most of his vacations as a kid traveling to England, where he worked out with Sunderland. That resulted in an offer to enroll in the Black Cats' academy and at the age of 20 his debut with the first team in the EPL.
He told the Guardian recently he has a lot of pride representing the USA for which his only previous appearance came in 2015 Concacaf U-20 World Cup qualifying.
With Guzan not called in and Cameron Carter-Vickers and Gedion Zelalem called into the U.S. U-20s, Gooch and veteran Geoff Cameron are the only players from the EPL in the U.S. squad.
"Some of the players really deserve a look," Klinsmann added. "Lynden Gooch is a very talented, young player coming through at Sunderland. Danny Williams has had an outstanding season so far for Reading. So you have some players that you would just love to have a closer eye on for those 10 days, and this is the opportunity now to do that. We’re very curious to see how they perform.”
