Cong An Ha Noi won 3–0 at Dong Nai on September 20, with all three goals arriving in a short burst after halftime. For readers following Vietnam’s top division, the key was how an early dismissal and a waterlogged field changed the problem each team had to solve.
The match turned before the goals arrived
Le Van Son was sent off in the 16th minute following an incident involving Nguyen Dinh Bac, who received a yellow card. Dong Nai nevertheless reached halftime without conceding.
According to VnExpress’s match report, heavy rain encouraged both sides to use aerial balls. Alan and Perea scored headers in the 52nd and 55th minutes; Le Pham Thanh Long added the third in the 58th. CAHN finished the evening with three wins from three league matches and no goals conceded.
Why the delivery matters
The tactical lesson is about the route to goal. A flooded surface can make a short pass unreliable: the ball may slow unexpectedly, forcing its receiver to wait while a defender closes. An aerial delivery removes that particular uncertainty, although it introduces a different contest in the air.
For a team defending with ten, covering the player delivering the ball and marking every runner are competing demands. Maintaining compactness helps protect central areas, but does not automatically prevent an opponent from finding crossing room outside the block.
That is a useful way to examine the two headers here. It is an interpretation of the reported events, not a claim that tracking data proves a specific defensive shape.
What to watch in the replay
Follow the defenders before the cross leaves the foot. Who steps out toward the ball? Who remains responsible for the runner behind that defender? Then watch the edge of the box for the next phase, where a clearance can become a second ball.
The score tells us CAHN made the advantage count. The better viewing question is how they turned extra space into deliveries that could survive the conditions.
