Borussia Dortmund are refusing all talk of being crowned Bundesliga champions despite a 3-1 win over Bayern Munich giving them a 12-point lead at the top of the table and prompting party plans in the city.
With ten league games left, Dortmund coach Jurgen Klopp is busy keeping his players' feet on the ground after beating defending champions Bayern both home and away this season and he refuses to talk about his team winning the league.
But after Saturday's victory over Bayern in Munich, Dortmund are firmly on course for their first league title since 2002.
In the football-mad city, officials are getting ready for potential celebrations on May 14 when Borussia host Eintracht Frankfurt in their last league game of the season.
"We are in the preliminary planning stage," Hans Werner Rixe, an events manager for the city of Dortmund.
"We are looking at a few things with regards to various aspects of security."
Traditionally, the champions celebrate their German league success by showing off the Bundesliga shield from the balcony of the city Rathaus -- or townhall.
But with a 150,000-strong crowd expected to turn out should Borussia win the title, the Rathaus square, Friedensplatz, in Dortmund may be too small.
"Of course, there is not enough space for 150,000 people at Friedensplatz, so we need to find an alternative venue (in the city centre)," said Rixe.
"It is still too early to look at the details, but security is of course a big concern.
"We are talking to the fire brigade and the police in the city."
Rixe revealed there have been talks with the football club, but fans travelling back to Dortmund for the May 14 finale could struggle to find accommodation.
Trade fairs in nearby Duesseldorf and Essen are being held the same weekend, while Duesseldorf's Esprit Arena is also hosting the Eurovision Song contest on Saturday night.
