The newly named Franz Beckenbauer Supercup has many uses. Unlike some of its continental counterparts, this curtain-raising meeting between league and cup winners tends to brim with a pleasing intensity. It unfolds in a partisan atmosphere too, taking place at one of the two competitors' stadium rather than at a neutral venue, so we feel the real straight away. Telling us what to expect for the coming nine months in the Bundesliga, however, isn't often one of the Supercup's strengths.
