Deliver and finish a near-post cross. Whip a low, driven ball across the face, attack the near post with a late run, and glance it across the keeper with a small deflection.
The winger drives to the byline and whips a low, driven cross across the near post. The striker times a late run to attack the near post and glances the ball across the keeper. Serve the ball hard and flat, and time the run to arrive as it comes. Rotate the winger and the striker, and vary the delivery height.
Whipped low and hard across the near post, a cross reaches the danger area faster than any other delivery and gives everyone defending it the least time to react. That speed is the point, and it is why this cross has to be struck rather than floated: the goalkeeper cannot come for it, the defenders are turning as it arrives, and the attacker only has to make contact.
The glance is a small movement. On a ball travelling that fast, the header is a deflection of a few degrees, which is enough to take the ball away from the keeper's starting position and inside the far post. Players who attempt a full heading action on a driven near-post ball usually miss it entirely, because the ball has passed before the neck action completes.
The run is the difficult part and it is a timing problem rather than a speed one. Arriving early means being marked and static in the zone the defender is protecting. Arriving late, from behind or outside the marker, means getting across him at the moment the ball arrives, and a defender cannot both watch the flight and track a runner behind his shoulder.
The pairing between deliverer and runner is what makes it repeatable. This is a rehearsed combination, not an improvised one, and the crosser should know before he looks up roughly where the attacker will be. Practising it as a pair, from both flanks, is what turns it into something a team can actually use in a match.
Save it to your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block. Or start from a blank pitch and build your own.
