Football's rule-makers have agreed to amend the offside law in a bid to reduce uncertainty for referees.

In a change to take effect from July 1, the International Football Association Board has attempted to clarify when attackers are influencing play.

The change states that an attacker should be considered offside when "gaining an advantage by being in that position." This will include receiving the ball from a rebound or deflection from the goal frame or a player in the defending team attempting a tackle, block or save.

IFAB, which comprises officials from FIFA and the four British football associations, also agreed Saturday that its decision-making would be improved by consulting more people within football.
