Borussia Dortmund must put thoughts of the Champions League to one side and focus on other competitions, according to their general manager Hans-Joachim Watzke.
Dortmund finished what was regarded as the toughest Champions League group with an unbeaten record, leaving Real Madrid, Ajax and Manchester City in their wake.
However, with the exception of a few hours on 20 December when the Westphalians will discover their knockout stage opponents, Watzke wants his club to forget about Europe until February.
``It's absolutely extraordinary what this team has achieved, but now that's enough of the Champions League,'' said Watzke in Kicker magazine.
``We must focus on the bread and butter.''
That means the Bundesliga and a home game against Wolfsburg tomorrow with 11 points to be made up on league leaders Bayern Munich if Dortmund are to successfully defend their title for a second time.
To that end, Dortmund can count on a significant confidence boost from Tuesday night's 1-0 win over Manchester City.
``Our team cannot be beaten when it comes to ambition,'' added Watzke.
They come up against a side whose pre-season ambitions have not been matched during the campaign so far.
The Wolves set their sights on a return to Europe next season, but instead they are still too close to the relegation zone for comfort and need points for a different reason tomorrow.
Their coach Lorenz-Gunther Kostner has been studying the best approach to take something away from the Westfalenstadion and knows his side will have to be careful.
``It would be crazy to say we will go to Dortmund and storm the bastions,'' he said. ``We need to be a bit more realistic.
``But what I do demand of my lads is absolute passion and tactical discipline.''
The Wolves had a scare in training yesterday when their playmaker Diego limped away with a knock, but the Brazilian could nevertheless be fit to face Dortmund tomorrow.
