Thomas Mueller scored a last-minute penalty for Bayern Munich to beat Augsburg 2-1 and Borussia Dortmund maintained its perfect Bundesliga start by defeating Hannover 4-2 on Saturday.

Hannover defender Felipe scored an own goal and gave away two penalties.

Alexander Esswein stunned Bayern when he struck for Augsburg two minutes before the break, but Robert Lewandowski equalized in the 77th and Mueller made no mistake from the spot after Markus Feulner was adjudged to have fouled Douglas Costa.

Pierre-Emerick Aubameyang scored both penalties for Dortmund, with Henrikh Mkhitaryan adding a fine strike and Felipe doing the rest.

Promoted Darmstadt upset Bayer Leverkusen 1-0 away for its first win, Hertha Berlin defeated Stuttgart 2-1, while car manufacturer-backed clubs Ingolstadt and Wolfsburg could draw only 0-0.
