Well it goes a little like this:-
Like most things in football the offside rule is pretty simple - that is until it gets changed each year.
An amendment to the rule was introduced at the start of the 2003/04 season, which allows a player to be in an offside position provided he or she is not "actively involved in play".
It was designed to promote attacking football, but different interpretations of what constitutes "active play" have led some to suggest it is open to abuse.
So ahead of this season Fifa, world football's governing body, has clarified when a player is to be regarded as "actively involved in play":
"Interfering with play means playing or touching the ball passed or touched by a team-mate."
You can expect to see what would appear to be very late decisions by assistant referees this season, as they won't raise their flag until a player touches the ball.
Of course, a player doesn't necessarily have to touch the ball to influence the play. They are still offside if they are judged to be:
Interfering with an opponent - If an attacker interferes with an opponent by either preventing them from playing or being able to play the ball, then they are offside. This could be done by blocking the goalkeeper, or obstructing their line of vision.
Gaining an advantage - If the ball is played into the penalty area and rebounds off either a post, the crossbar or an opposing defender, then the attacker is offside as they have gained an advantage by being in that position.
OFFSIDE ESSENTIALS
Got your head around the new rules? Here's our guide to the basics.
A player is in an offside position if they are nearer to the opposition's goal line than both the ball and the second last opponent.
Clear so far? There are a few more things to remember.
You can't be offside if:
You receive the ball directly from a goal kick, a throw-in or a corner;
you are in your own half of the pitch;
you are level with the second last or last two opponents;
you are not actively involved in play, as explained above.
For any offside offence, the referee awards an indirect free-kick to the opposing team, to be taken from the place where the infringement occurred.
I don’t fully understand it perhaps you should ask it’s not for girls for a second opinion.
