The 4 pass plan only worked because Ryuu dropped mid, giving a numbers advantage, causing chaos to the white team's midfield, then using the chaos Ryuu ran opposite the side of play opening himself up for the goal.
The reasoning of only playing defensively almost always never works, white team didn't even get the chance to shoot the ball in the first half because they constantly attacked the goal, give that up and now you give the white team a chance to score, and now that Ryuu gets to play possession, he's gonna tear it up!
