Pressure occurs when the attacking team is able to retain possession going forward through effective support play and winning the contact point, until it scores.
Pressure can be exerted from anywhere on the field.
By exerting pressure on the defensive team through the above mentioned ‘Principles of Play’ a situation will be created in which there are more attackers in a channel of linear space than defenders. When the ball is passed to the unmarked attacker the player penetrates and scores.
The same principles create situations which provide the ball carrier with plenty of space to attack a single defender which is often enough space for the attacker to penetrate.
