Bayern Munich v Borussia Dortmund: Klopp aims for Bayern boost

BBC Sport's John Bennett visits Borussia Dortmund, who go into Saturday's match against Bayern Munich looking to turn around their poor league form.

Dortmund, last season's Bundesliga runners-up, travel to the Allianz Arena 14 points behind the champions after six league defeats in the first nine games, a run that has left them in 15th place.

Bundesliga leaders Bayern are unbeaten in the league and Champions League this season.
