In soccer, "fouling" refers to committing an infraction against an opponent, typically involving illegal physical contact such as tripping or pushing. Fouls may result in free kicks or penalty kicks awarded to the opposing team, depending on the severity and location of the foul on the field. The referee has the authority to assess fouls and enforce penalties, which can significantly impact the game's outcome. Maintaining discipline and avoiding fouls is essential for players to ensure their team’s success.
