Borussia Dortmund’s young stars made a flying start to the new Bundesliga season with a 3-0 victory over Borussia Monchengladbach. Two teenagers combined for the opening goal on 35 minutes, as Jude Bellingham marked his league debut with an assist for Giovanni Reyna. Reyna then earned his side a penalty after the break, which Erling Haaland tucked away before adding the third after Jadon Sancho's electric counter-attack.
