Werder Bremen Vs Borussia Dortmund on Friday knowing defeat could deal a further blow to their opportunities of stopping Bayern Munich steamrolling their way to a 23rd Bundesliga title.
Jurgen Klopp's side ended last season 10 points clear of third-placed Bayern, but they already lie 6 points adrift of the Bavarians, and 3 behind Bremen, with just 8 games of this campaign played.
For Klopp, Werder Bremen Vs Borussia Dortmund is simple: to compose a team "which is capable of bringing the points back from Bremen."
Dortmund have a busy few weeks ahead of them, including a vital UEFA Champions League doubleheader against Olympiacos.
They signed off before the international break with a confidence-boosting 4-0 win over Augsburg. Polish striker Robert Lewandowski scored a hat-trick in that rout, but his place in the starting line-up at the Weserstadion is under threat from Lucas Barrios, the Paraguayan striker who is fit again after a two-month injury lay-off.
Meanwhile, Dortmund's teenage midfielder Mario Goetze, who scored the fourth goal against Augsburg, was inspirational in Germany's 3-1 win over Turkey in their final UEFA EURO 2012 qualifier in midweek.
