Players who deliver balls this way are normally acknowledged as a crosser.
The intention is to produce a cross, which is airborne and is high. This allows teammates, who are receiving the cross, more time to predict where the ball is going to be and position themselves for an attempt to score a goal; conversely, this allows the defending team's goalkeeper to prepare for the deflection towards goal, or run and capture the ball with his or her hands.
Normally, this type of cross is implemented, when the team usually has tall players due to their obvious aerial invincibility, or when the crosser is near the goal line, where curving the ball may be difficult.
Inswinging crosses usually arise, when a player who is right-footed is on the left side of the pitch (or who is left-footed and is on the right side of the pitch) and prefers to cross with the inside of his or her dominate foot, as using the outside of the foot is hard to direct.
The position from where the cross is delivered from can vary; it can be from the goal line, requiring the ball to be aimed further away from goal; it can also be from a deep position, where the curl produced will direct the ball towards goal.
Many players, when running past defenders, along with support in the center, will find this variation easier and successful; in this case, the player has his or her dominate foot with agreement to the flank they are on (i.e. right-footed player on the right-side of the pitch or a left-footed player on the left side of the pitch). The crosser can simply use the inside of their dominate foot while running.
The simplicity allows the crosser to produce curve and height to their desired teammate. The curve away from goal makes it difficult for the opposing goalkeeper to capture; however, the receiver has to be skilled with one-touch skills and prediction, as the outswinging cross requires more effort and precision to be converted into a goal.
Positions for where this type of cross is delivered from vary. Because it is the inverse of a inswinger, it is aimed closer to goal to deceive the goalkeeper in both cases.
It is simply a push pass from close range that travels along the ground. This allows central receivers to quickly use their feet to score a goal. The deception to this is that the defenders find it mundane and can plainly intercept the ball and kick it away. However, the low cross may also have partial spin or may not be a soft pass. Many players find varying their crosses makes it difficult for the opposing team to predict and this is the alternative.
Low crosses may also be a result of poor level of skill, where players do not have the ability to kick a ball with the correct conventions, although at a profession level, low crosses may be less probable for poor skill and more so mistakes.
This variation can also be instituted when the team's aerial game is poor, but their agility and ball skill with their feet prevail.
