Borussia Dortmund coach Jurgen Klopp opted for Australia goalkeeper Mitchell Langerak over Germany's Roman Weidenfeller for Friday's 'High Noon' showdown against Hoffenheim in the Bundesliga.

The Socceroos shot-stopper has been used as an understudy since joining Dortmund in 2010 and only previously played when World Cup-winner Weidenfeller had been either injured or rested.

But with Dortmund bottom of the Bundesliga after losing eight of their first 13 matches, Klopp opted to give Langerak only his 12th appearance in the German top flight with Weidenfeller left on the bench.

Klopp described the clash with Hoffenheim as 'High Noon' for his team as they look to bounce back from a dire run of league results which has overshadowed their campaign despite their qualifying for the last 16 of the Champions League.
