The U.S. men's national team is gathering for the first time since the winter for friendlies in Europe vs. Wales and Panama. Gregg Berhalter has called on a young team, whose average age is just under 22 years old. Of the 24 players in camp, 10 are uncapped, including rising Borussia Dortmund star Gio Reyna. Christian Pulisic has been labeled as day-to-day after suffering a hamstring injury with Chelsea and may not feature in the matches. The most intriguing name in camp is 17-year-old Valencia midfielder Yunus Musah, who also maintains eligibility for England, Italy and Ghana.
