Police have banned 20 potential troublemakers from attending the Rhine derby between Bundesliga rivals Cologne and Borussia Mönchengladbach on Saturday and plan to safeguard the game with over 1,400 officers.

Authorities still expect around 500 people from both sets of fans who may be prepared to use violence. Police said in a statement on Thursday that they would "keep a particularly close eye" on such supporters.

The rivalry between the two clubs has been huge since the 1970s and neither side is safe from relegation ahead of the 100th meeting, making the game even more important.

Cologne coach Lukas Kwansniok was confident that his side would avoid the drop, saying on Thursday that "we will reach our goal."

In addition to the derby on Saturday, emergency services will also be stretched by a parallel demonstration against racism in Cologne, with around 10,000 people expected.

Police are anticipating traffic chaos, with numerous road closures in the city.

German politicians are mulling the idea of billing clubs for policing costs or denying permits for football events after a rise in violence in and around German matches.

Cologne managing director Philipp Türoff rejected "blanket threats" as not helpful.

"They demonstrably do not represent an effective lever for more security, but risk undermining the partnership-based cooperation between clubs and authorities," he told Kicker magazine.

German state sports ministers did not mention this issue after a meeting on Thursday.

But Hamburg's sports senator Andy Grote spoke of "a danger that a tipping point has been reached" after ministers accused the German Football League (DFL) and federation DFB of being too lax regarding stadium bans.

“We will not tolerate rioting or violence in or around stadiums. We will give the conference of interior ministers our full support so that we can reach appropriate agreements with the DFB and the DFL,” sports minister conference chair Theresa Schöpper said.

Fan groups have meanwhile criticised excessive force used by the police which makes them suspect that this is designed to show an alleged increase in violence in police statistics.

Kwasniok steadfast

Cologne coach Lukas Kwasniok is adamant his side will stay up having previously predicted survival. They are one point above the relegation play-off spot.

"I stand by it: We will achieve our goal," he told a news conference despite six matches without a win.

The boss, in his first season in charge, has been under pressure from elements of the fanbase all season but said he was still the man for the job.

"Cologne were relegated from the Bundesliga for the first time in the 1997-98 season. We have gone down seven times," the 44-year-old said.

"In those seven times, they always tried to prevent it with coaching changes and it didn't work."

Top scorers Said El Mala and Jakub Kaminski are fit to play in the 100th Bundeliga derby between the rivals despite missing training on Wednesday.

"They rested yesterday but took part in everything today. They can be involved as normal," the coach said.
