Argentina is a big scorer, bet over 2.5 goals will be a wise choice and USA also keep on scoring in the last matches, so i will bet both team to score, for this match i think Argentina is still too tough for USA so its a slim chance that USA is going to win this match
USA will not be defeated easily as you think they would be, they still got some pride that they need to defend, afterall they are the host for copa america so if they just lose that easy to argentina then it will be lame for the fans. The USA fans is a tough crowd so they could be an additional player that could help USA in winning it
