When you decide to play with "defensive mentality" (press the keypad 5 until the triangle is pointing down) you opponents will likely to face a "bunker"-style defense. Practically, all 10 outfield players will defend, positioning themselves on the own half of the field - especially when opponent has the ball. The area between the central line and your penalty area will be relatively free and "open" (watch out for long kicks), but close to the 20-meter line your midfielders will face opponent attackers, with your defensive line further closer to the goal. Your opponent will have practically no problem passing the ball in midfield (and even in attack) – but it will be very hard for him to get a good shot, as the penalty area would be loaded with defenders. Also, it must be noted that it seems that the game "reacts" for defensive formation in a special manner – your goalie will be making more saves and more shots will miss the target. Used with "counter attack" option (PART I – offensive tactics) the "defensive mentality" can be a serious weapon while defending a lead. However, I would not recommend on using it for the whole match as the opponent will, finally, find some "holes" in your tight defense – and score.
