Dortmund head into this one sitting second in the Bundesliga, but their recent form carries a note of caution — two defeats in their last five at home temper what looks like a strong position on paper. That said, their home defensive record has been quietly impressive this season, keeping clean sheets in over half their home games and conceding under a goal per match on average, well below the league norm.

Frankfurt are the more intriguing story here. Their away BTTS rate of 87% dwarfs the Bundesliga average of 60%, and they have kept just one clean sheet on the road all season. They arrive having scored nearly two goals per away game, meaning they tend to bring life to fixtures even when results go against them. The sole H2H meeting this season ended in a draw, hinting at a competitive dynamic between these sides.

The data suggests Frankfurt's away profile makes this a more open game than Dortmund's home numbers alone would imply. This one looks more goal-laden than the hosts' defensive record might suggest.
