For players looking to gain an advantage, it is recommended to analyze the chances of upcoming opponents. Make note of specific situations such as 'shot on the left,' 'shot on the right,' 'breakthrough with ball on the left,' 'breakthrough with ball on the right,' 'breakthrough without ball on the left,' and 'breakthrough without ball on the right.' Keep track of these chances and mark them if they result in a goal. This will help identify patterns in the opponent's playstyle, which can be used to your advantage in defense.
