The 22-year-old dedicated the goals to his family back in America, where he grew up.
“I am happy for the result and for the double,” Rossi said after the game. “I dedicate my goals to my family who are watching the game on TV in America.
“When I came on the team were suffering. The USA are tough. They run and fight a lot, but in the second half they were tired.
“Now we can have a great tournament,” Rossi concluded.
