Bayern Munich extended their unbeaten run to 38 games as they crushed title rivals Borussia Dortmund 3-0 at the Signal Iduna Park.
Former BVB fan favourite Mario Gotze came back to haunt his old club as he came off the bench to open the scoring in this top of the table clash.
For the opening hour both sides struggled to create any clear cut chances with Polish striker Robert Lewandowski wasting the best chance of the first-half when he fired over from close-range and should have at least hit the target.
Marco Reus did force a save out of German international goalkeeper Manuel Neuer when he broke through the Bayern Munich defence and forced a save out of Germany’s number one.
Mario Mandzukic had the best chance of the first-half for the visitors when he acrobatically got on the end of a Arjen Robben cross from the left, but the Bayern striker could not open the scoring.
Pep Guardiola then introduced Gotze to a chorus of boos from the home fans in the second-half and the former Dortmund player made an immediate impact. The €37 million midfielder finished to the far corner with the outside of his boot after combining well with Thomas Muller and open the scoring with 66 minutes played.
Reus again forced a save out of Neuer as BVB pushed forward in search of an equaliser, before Henrikh Mkhitaryan shot wide from close range.
Bayern then killed off the tie by doubling their lead in the 85th minute when Robben broke clear of the host’s defence and applied a fantastic chip over Roman Weidenfeller in the Dortmund goal.
Last season’s treble champions then wrapped up their first win in Dormund since 2009 when Muller made it 3-0 when he got on the end of a Phillip Lahm cross.
