Niko Kovac named arguably his strongest side possible but his team struggled to create chances against diligent and organised opponent until late on, eventually winning 1-0.

Thomas Muller thought he had opened the scoring with 12 minutes to go, only for Franck Ribery to be adjudged offside, before Lewandowski finally put Bayern ahead by diverting Leon Goretzka's shot home.

Nevertheless, it was hardly a convincing performance from Kovac's men ahead of their Bundesliga opener next week.
