MUNICH, Oct 19 — Forward Harry Kane scored once and helped set up another as champions Bayern Munich battled past Borussia Dortmund 2-1 in the Bundesliga’s Klassiker yesterday to maintain their perfect start to the season with their seventh straight win.

The Bavarians, who host Club Brugge in the Champions League on Wednesday, had to survive considerable second-half pressure from the visitors before making sure of their 11th win in 11 matches across all competitions this season.
