GD in football points table stands for “Goal Difference.” It is a measure of the difference between the number of goals scored and the number of goals conceded by a team in a football league.
Goal difference is used as a tiebreaker in case two or more teams have the same number of points in the league table. The team with the higher goal difference will be ranked higher.
For example, if a team has scored 30 goals and conceded 20 goals, their goal difference would be +10. If another team has scored 25 goals and conceded 15 goals, their goal difference would be +10 as well. In this case, both teams would have the same number of points, but the team with the higher goal difference would be ranked higher in the table.
Goal difference is an important statistic in football as it reflects a team’s attacking and defensive capabilities. A positive goal difference indicates a team that is scoring more goals than they are conceding, while a negative goal difference indicates the opposite.
You can find the goal difference column in a football points table alongside other columns such as points, matches played, wins, losses, and draws. This column helps determine the overall ranking of teams in a league.
