There seems to be a misunderstanding. Fluminense is a Brazilian football club, while Borussia Dortmund (BVB) is a German football club. These two teams are not in the same leagues or confederations and therefore, do not typically play against each other. A match between Fluminense and Borussia Dortmund would be a rare friendly or exhibition game, not a regular competitive fixture. As such, there isn't readily available information or a history of matches to summarize.
