BERLIN — European champion Bayern Munich took a significant step toward retaining the Bundesliga title with its first win at rivals Borussia Dortmund in four years. Former Dortmund hero Mario Goetze came off the bench and produced a super shot to give Bayern the lead on 66 minutes before Arjen Robben and Thomas Mueller added to the 3-0 rout in the final five minutes of Saturday's German Clasico. It was Bayern's first Bundesliga win over Dortmund in seven attempts and extended Munich's record unbeaten run in the German league to 38 matches in a repeat of May's Champions League final. The result at Dortmund's Westfalenstadion left Bayern four points clear of Bayer Leverkusen, which replaced Dortmund in second place, while Pep Guardiola's Munich is an ominous seven points ahead of Borussia.

Zlatan Ibrahimovic scored his ninth league goal to seal the win in stoppage time. Reims midfielder Grzegorz Krychowiak missed a penalty in the 68th. PSG has not lost since March at Reims, 1-0.
