Choose your delivery technique ( I use "driven" ) then choose 'near post', it should be the circle button. Drag the player you have selected (at the near post) away from his marker toward the corner kicker. The distance of your goal scorer to the marker is crucial!! I drag my player until he is equal distance from his marker and the side line of the 18 yard box ( a little over 2 yards in real life play) once you have him dragged into position THAT'S IT! don't do anything but head it into the goal, don't try to move the attacking player, You'll notice as the corner is taken your attacker runs into position and heads it in, everytime!
