The Spanish striker, who impressed for his country at the Under-19 European Championship earlier in the summer, is one of the players from Madrid's youth ranks who have been given the chance to prove their worth to coach Jose Mourinho during the warm-up preparations.
Jese, who also joined up with the squad last summer, had expressed confidence that the Portuguese coach would not overlook the club's homegrown talent this time around, and he took to Twitter to share his emotions before leaving for the States.
"About to go to Los Angeles with the entire first team," he wrote. "It is a luxury to be able to make the pre-season again and to be able to work with them."
Los Blancos' first match on American soil is scheduled for August 3, against LA Galaxy.
