To help yourself relax, develop a ritual that will help you concentrate and allow you to get off a better kick each time. He goes through a ritual and does the same thing every time. It enables him to get into a set routine and concentrate on what he is doing. Loose man-marking is a common problem in all levels of soccer. Nearly every time a goal is scored, it can be traced to the moment when somebody let their man go free.
Marking is an individual skill much like dribbling, trapping, heading, shooting or passing.
And it's something you can improve. There are three things to remember when your job is to mark. First, don't let your player get the ball. You can do this by staying ball side and goal side of your man. That way, you're always in a position to step in and get the ball before your man does.
