From here the counter attack can be sprung. This system brings about opportunities for many attacks, as you win the ball in positions higher up in the field. The opposition will also be stretched defensively as they try to find a way out of the "press".
The key to a successful side is to attack using the full pitch and defend in as small a space as possible. By closing the oppositions' space when they are in possession, closes down the angles and options they have available to them. If they try to carry the ball out of this position, it is important that we try to channel the ball carrier onto a second defenders stick to make the tackle. If the first defender dives in, it is very likely that the ball carrier will win the hit and thus obtain the space and time he was looking for. It is crucial that both defenders know that they are looking for this double defence and work accordingly.

Reasons for the Zonal Defence
1 To place the opposition in areas of the pitch with very few options
2 Be able to win the ball higher in the pitch
3 Avoid the defenders chasing needlessly after opposition forwards.

A coach once told me that by using a small amount of mental energy, you save yourself a huge amount of physical energy. I.e.: More you think the less you have to run, thus saving yourself energy for when it is actually needed.The system does take time to perfect, and the keys are to communicate well, and react quickly to situations. I call this an "Allplay", as all 11 players are involved, and if 1 person is not aware or fails in his role then the opposition can find a way out of the pressurised situation. There is no place for man-to-man marking in this system, except if the attackers near the defensive 25-yard line. Here a lot of teams will now change to the man-to-man system, as before communication is the critical part of the equation to ensure a successful transition.
