One of the Best ways to effectively score against opposing teams is by using a set piece called the Short Corner. This miniature scheme isn't much more than swinging the ball into the box, but, believe it or not, it can actually help draw defenders away from the net when used with regularity. This will help create space for the attackers on your team, allowing them to exploit the holes in the opposition and score with frequency. This trick has been used by many Players for many previous installments of the Football Manager Series, and it continues to produce incredible results in Football Manager 2018.
However, do remember to mix up your corner routines with some form of consistency, as it will prevent opposing teams from learning your favorite Tactics and schemes. You can't rely solely upon the same form of offense game in and game out, and that includes the Short Corner Setup. Even if you have great success with it, the Best of teams will quickly begin to figure your ball club out and thus will better prepare to stop you from doing so on game day.
