The Laws do not stipulate any rules or procedures for crediting goals to players, and indeed such records are not a compulsory part of the game. In 1997 FIFA issued detailed guidelines for crediting own goals, recognising the increasing commercial importance of statistics such as top scorer awards and fantasy football. The guidelines state that credit for scoring is decided by the referee, or match commissioner if present; and " defender's intervention must be deliberate in order for an own goal to be registered against him". Regarding a shot which deflects or ricochets into the goal off a defender, some sources credit the score to the attacker; others count them as own goals; for others it depends on whether the original shot was off target; others are more nuanced. There was controversy in 2013 when the FA Premier League credited Tim Howard with an own goal when a shot came off the post, hit him in the back, and went in.
