Don't be so pessimistic! I'm French, but I live in Germany, so I see all the DC ties of the German team and Germany usually sucks big time in Davis Cup!!
I don't know exactly why (Kühnen seems pretty lame to me, there are some rivalries in the German team too...) – anyway, they always struggle horribly against very average teams (Belarus on clay, South Africa, Czech Rep. with Zib as a single player...), it's painful to watch!
I know Kiefer and Haas are playing much better now than last year, but they always manage to have troubles against teams which are supposed to be much weaker, so I think this tie will be pretty even.
C'est loin d'être perdu d'avance, allez!
