If the game is played with the limitation that you have maximum 3 touches and you cannot score from a breakaway or long forward pass. They will beat our U20 easily. The advantage the men have over the women is speed and physical.
if you set limitation to remove that advantage and the game comes down to passing, movement off the ball tactics and positioning, the women taking it to we easy at the youth level.
That Japan team will destroy any tnt youth national team in a 20 by 30 small goal field.
Most of our teams dont grasp the concept of "play and move"
