Sarachan said he's been working with a list of 35 players.
"It's a work in progress," he said. "We're sort of paring it down as we've evaluated players both here and domestically and overseas."
Teenagers Christian Pulisic, Weston McKennie and Tyler Austin along with central defender Matt Miazga will form a corps of young players around whom the team will be build.
The big question is whether he will recall veterans like Michael Bradley, who captained the USA when it failed to qualify for the 2018 World Cup in the last cycle but did not play in the six friendlies the USA has played since qualifying ended with a 2-1 loss to Trinidad & Tobago. Sarachan said he talked with Bradley recently and the Toronto FC midfielder understands where he is coming from.
"I've known Michael since he was little," Sarachan said. "We talk often and we did speak recently. I've made it pretty clear over the course of the months that I've had the team that the focus right now has been to offer opportunity to a lot of our young players. But we're not discounting the value of veteran leadership and Michael falls into that category."
