Bayern Munich have taken a step towards extending their unbeaten run after Thomas Muller handed them a 1-0 half-time lead over Eintracht Frankfurt.

Frankfurt enjoyed a spell on top early in the match, but were restricted to speculative efforts by the visitors, with Alexander Meier firing over from the edge of the box.

However, the World Cup winner would make up for his miss by giving his side the lead in the 23rd minute with a simple finish from close range after seeing his initial effort from Franck Ribery's blocked by Felix Wiedwald.

Wiedwald was forced into action to prevent the hosts from falling behind before the break as Dante watched the Frankfurt shot-stopper push his powerful header over the crossbar.
