"This is going to be an incredibly difficult match up, very challenging," said Morgan, who is competing in the tournament for the fourth time.
"We watched the Netherlands the other night, and they have a lot of the same players as we played them in the World Cup four years ago."
The American defence was solid in their 3-0 opening win over Vietnam on Saturday, scarcely letting the World Cup debutants into the final third.
But the U.S. spurned several chances to find the net and Morgan, who failed to score a first-half penalty against Vietnam, conceded that there is room for improvement.
I feel like some of the plays that we had were a little forced or rushed," said Morgan.
