Attack in the middle
Attack in the Middle (AIM) is one of the game's tactics. It raises the probability that a chance is created in the middle of the field by at least 20%, lowering at the same time the probability that a chance is created on the wing.
It is believed that the usual distribution of chances between left wing, center, right wing and set pieces (including penalties) is 25%-40%-25%-10%. Playing AIM would change it to 21%-48%-21%-10% (if the ability in the tactic is low) or to 17%-56%-17%-10% (if the ability in the tactic is the highest possible). The ability in the tactic is calculated by summing the Passing ability of all your outfield players.
The drawback of the AIM tactic is a weakening of the wing defence.
Your ability to turn wing attacks into attacks through the middle is influenced by the total passing skill of all your outfield players. When calculating your AIM skill, an experience bonus is added for each involved player, as normal.
With an exceptional AIM skill, you will get something like 40% more attacks through the middle. At a minimum you are guaranteed to get 20% more attack through the middle. Depending on your AIM skill, you will end up somewhere in between these two extremes.
So do remember to AIM if you want a good central attack.
The AIM tactic is not reported with events like counter-attacks, and lost opportunities are detailed only for the tactics above. The only indication that a player is using AIM is at the start of the game report and in the match ratings. The game, however, keeps adding a modifier throughout the match.
