A player in an offside position at the moment the ball is played or touched* by a team-mate is only penalised on becoming involved in active play by:
interfering with play by playing or touching a ball passed or touched by a team-mate or
interfering with an opponent by:
preventing an opponent from playing or being able to play the ball by clearly obstructing the opponent´s line of vision or
challenging an opponent for the ball or
clearly attempting to play a ball which is close when this action impacts on an opponent or
making an obvious action which clearly impacts on the ability of an opponent to play the ball
