In the middle of the stressful weeks, the processing of the scandalous events in Malmö by the leaders of the Bundesliga also bursts.
UEFA is likely to get involved, but those responsible at 1. FC Union Berlin also want to find those who were responsible for the interruption of the game with the Swedish record champions.
"We will evaluate that with the scene, that's very clear," announced club president Dirk Zingler: "In the end, there are always few.
It may sound like a cliché, but it is the truth.”
It was unclear on Thursday who exactly threw what before the team made their way back to Berlin after the first win in the Europa League thanks to a goal by Sheraldo Becker (68th minute).
But Zingler said: "If we invite guests to our blocks, we have to have everything under control.
There is now a need for clarification.” Union fans had invited people “from the village”.
However, he did not elaborate on these statements.
“It's a tarnished victory.
It is unacceptable.
Nothing and no one has anything to do on the lawn or in other blocks.
That totally annoys me.
We don't know it, we don't do it and here we suddenly do it.
I'm pissed about it," he said on RTL+.
Zingler has no worries that there could be problems again in the second leg next Thursday in the stadium An der Alten Försterei, which will surely be sold out.
"I think we can handle situations like this better," emphasized the 58-year-old.
"Pyrotechnics on the field"
He also didn't want to "reproach" hosts Malmö.
But he didn't like the fact that you had an incredible amount of freedom and could have moved as you wanted.
On site, however, it was initially unclear who ignited and threw the pyros and fireworks.
"Both camps threw pyrotechnics onto the field," said the Unioner, whose head of communications, after the international announcements, also talked to the Köpenick supporters again before the game continued.
TV footage also showed security forces bringing fans from the stands who weren't in the Union supporters' block.
The team will recover a little from the trip and the game with a regeneration session on Friday.
There can be no sign of recovery behind the scenes.
It is surprising that the Irons, of all people, who are known and famous for their impressive atmosphere at home games in the An der Alten Försterei stadium, make negative headlines through fan riots.
Just recently, fans of 1. FC Köln and Eintracht Frankfurt caused massive negative headlines in their European Cup games.
“Aiming fireworks at people, pointing them at people, that just goes too far.
That's the bad thing: it's no longer about sport, about football.
That a minority just keeps getting it not to talk about the game.
Words fail me!
I find that shameful," said coach Urs Fischer.
The Berliners will play their next game away again on Sunday (7.30 p.m. in the FAZ live ticker for the Bundesliga and on DAZN) in the Bundesliga at VfB Stuttgart.
Only around 1200 fans had tickets for the game in Malmo.
Whether and to what extent fans of city rivals Hertha BSC were also in Sweden could only be speculated about for the time being.
The friendship of the FF supporters with those of Hertha is at least known.
Pyros and firecrackers caused an interruption of around 25 minutes after the restart, a firecracker exploded loudly and violently in front of the Union fans' block.
When it started again, Becker scored the goal – Union's first in the Europa League after two previous 1-0 defeats.
And still outnumbered after a red card against Andras Schäfer (45th).
"It was a roller coaster ride of emotions.
Chances, a red card, the interruption, then the lead and the win," said Union captain Christopher Trimmel.
But that's not the end of the game for 1. FC Union Berlin.
It was clear that referee Halil Umut Meler from Turkey only started again on probation after the interruption in the 57th minute.
If objects were thrown from the ranks into the interior again, the game would be stopped immediately, it said.
Becker gestured accordingly when a flare burned in the stands after his celebrated goal.
Not many suspected that the Unioners would score through Becker in the situation.
The guests had to take a hit just before the break when Schäfer saw the red card.
The entire Union team had gathered in half of the Swedes, then Schäfer stumbled the ball and involuntarily played it with his heel in the direction of his own goal.
Malmo's captain Anders Christiansen sprinted in between, Schäfer held his jersey and Christiansen fell.
The referee showed the red card: Schäfer was the last man to clearly thwart a goal chance.
After the scandal, that was just a side note.
