Werder Bremen say they would understand if Germany's Euro 2016 qualifier against Gibraltar in September were to be moved away from their Weser Stadion home.
The German Football Association (DFB) will on Friday decide whether or not to relocate the game to another venue after the Bremen state government ordered the Bundesliga club and the German Football League (DFL) to cover the costs of additional policing for so-called "at risk" games in future.
As the organiser of Germany's clash with Gibraltar, the DFB would therefore be requested to cover any additional security costs themselves, which is why they have now threatened to take the game elsewhere.
"It would be a very harsh, but a consequential decision," Bremen's general manager Klaus Filbry told the club's official website. "It's just saddening that, in the end, it's first and foremost the fans, but also Werder Bremen, the local economy and tourism in the region which has to bear the brunt of this unique political decision.
"These are precisely the ramifications we had been warning people about in our talks over recent months."
Should the local authorities succeed in approving their plans, the DFB would see no alternative but to take the game away from Bremen and not allocate any future matches to the city. It would also have an effect on the Bundesliga club's budget for the upcoming season.
Werder have condemned the proposal, with Filbry saying: "The decision [by the state government] to go it alone and break away from a community based on solidarity, in which there is cooperation between security authorities and Werder Bremen, leaves us really shaking our heads in disbelief."
"People are saying that the DFL should be ordered to pay this money, but there are clear signals from the DFL that it would be SV Werder who would have to foot the bill, because it's only understandable that all of the clubs in the league should not have to pay for one controversial change of law in the smallest state in the country.
"The competitive disadvantage and higher ticket prices which would result from this are surely not what anybody in Bremen wants."
