I love watching football. I have an interesting doubt. Did the Own Goal(OG) scored by the player(obviously by mistake) adds to his career stats? OR Its ignored?
Own goals do not contribute to offensive goal statistics and are simply counted as a different statistic altogether, as you said "OG". This statistic would be tracked throughout a players career however, and a full description of the exact rules regarding own goals can be found here.
No, first of all, exactly because considering the one player and team's perpective, is not considered a goal scored, but a goal against.
You see, the underline tone of football is movement: it's the movement that decides almost all if not all rules of the game.
Because of this, the movement resulting into one own goal is never considered a direct action by one player, but an involuntary one. That's why the own goal is a special kind of goal: for instance, that is the main reason why one player cannot score an own goal directly from a free kick (a corner is given to the opposing team), but he can score if he kicks into the the opponents’ goal.
Regarding statistics, usually at the end of each season, all the o.g. are sometimes anonymously summed up together to the list of all goals scored by one particular team, sometimes the names are present, out of curiosity.
