ESPN FC's Steve Nicol reacts to Borussia Dortmund's staggering loss to Bayern Munich, and notes that the Bundesliga may be already won. The supposed "Klassiker" turned into a damp squib as Bayern Munich stretched their lead to seven points at the top of the table with a crushing 5-1 defeat of nearest challengers Borussia Dortmund. Thomas Muller scored twice in the first 35 minutes before Pierre-Emerick Aubameyang replied with what proved to be a mere consolation for the visitors.
