Dortmund visits Union Berlin at 8.30pm on October 17 in Vietnam time after an unbeaten Bundesliga start. Bong Da Plus records four wins and a draw from five rounds, giving Niko Kovac's team 13 points and second place at the time of its preview.
Union needs defensive protection
The hosts have one league win. Results discussed include losses to Leverkusen, Schalke and Bayern before a 1-0 victory against Elversberg.
Union has scored five and conceded 17. The analysis therefore emphasises compact positioning, fewer midfield turnovers and efficient use of set pieces. Those are tactical requirements rather than events already observed in the forthcoming fixture.
Dortmund brings greater balance
The visitors beat Stuttgart 1-0 and Paderborn 3-0 before drawing 2-2 with Werder Bremen. Four goals conceded across five rounds support the report's more positive defensive assessment.
Serhou Guirassy is identified as an attacking focal point, with Felix Nmecha and Julian Brandt providing support. Their discussion does not confirm the final formation.
Emre Can remains unavailable after a knee injury, while Julian Ryerson requires time out with a rib problem, according to the preview.
Across 17 meetings, Union has four wins, two draws and 11 defeats. At home, however, the eight-game sample is split at four victories each.
That provides a different historical perspective without deciding the result. Dortmund must carry its form into another away test, while Union aims to build on its latest victory and reduce the spaces opponents have exploited.
