The team AS Adema is in the Guinness record books as having scored the most goals in an association football match. Which AS Adema player scored the most goals in the match?

The answer to the question is "no one". This stunning scoreline is from a match played in Madagascar:

AS Adema 149-0 SO l'Emyrne

Apparently SO l'Emyrne lost the match on purpose, as a protest against a history of poor refereeing decisions. The SO l'Emyrne team scored 149 own goals and disciplinary action was taken against members of the losing team. The Guinness Book of Records lists this as the highest score in any soccer/football match.
