What you saw was a clinical display of a top side like Argentina who wasn't messing around and took out the USA by forcing them to give up the ball with unforced errors on passes and consistent pressure to take advantage of all situations.
A record breaking goal from Lionel Messi and taking advantage of players who were in poor position as well as forgetting who to mark when the ball was delivered. For the USA it's not a shame to lose to a great team like Argentina, but unfortunately, they had no answer for what was being done in front of them.
