The Black and Reds, currently fifth in the Bundesliga, face a team in East Berlin with an outstanding record at home: Union have won four of their last five home games at the An der Alten Försterei Stadium, all without conceding. “They are a different opponent compared with Dortmund. They have their own strengths, particularly in defence,” said Bosz about the next opposition.
The fact Union Berlin are also the opponents in the DFB Cup quarter-finals in three weeks is not relevant at the moment according to the Dutchman. The 56-year-old said: “I only look at the next game and we have to fully focus on that. And who knows who will be playing for either side in the cup tie.”
The Bundesliga away game in the capital marks the start of a busy period of fixtures over the next three weeks. “We won’t have much time to recover,” said Bosz. The head coach was happy to see recent absentees Kerem Demirbay (suspended), Julian Baumgartlinger, Exequiel Palacios and Charles Aránguiz (all injured) return to full training this week.
It is looking good for the Chilean after his long injury lay-off but it remains to be seen if he will play. “Charly said he didn’t have any problems yesterday. But he hasn’t played since the start of January so we’ll have to wait and see what happens in today’s session. I’ll make my decision after that,” Bosz explained. “Perhaps all four will be available for selection.”
With a win against Union Berlin, Bayer 04 playmaker Kai Havertz can clock up his 50th Bundesliga victory – and all that at just 20 years of age. At the pre-match press conference, the head coach praised the development of the Germany international since the start of the second half of the season. “We’ve all seen that the Kai of last season is back. Against Dortmund, you could see he is very important to the team,” said the Dutchman who was also able to welcome back Paulinho yesterday.
The Brazilian was in Colombia where he helped the Selecao U23 team qualify for the 2020 Olympic Games in Tokyo. Bosz finished by saying: “That means all players are available as of now. That is very important in view of the run of fixtures coming up.”

It was another incredibly close call in the end: The second showdown in the 2026/27 VBL Club Championship saw the #B04eSports team once again narrowly miss out on a place in the top 16 of the preliminary round – and with it, a spot in the in-person knockout stage. It was a bitter blow: Marc and Sean Landwehr again fell just short, despite being level on points with their rivals. As was the case last month, their weaker record across the twelve individual matches in the six preliminary round fixtures proved decisive.

“They stuck with us over the past few weeks when things weren’t going so well,” said captain Edmond Tapsoba, thanking the fans for their support after the 2–1 win in Cologne and dedicating the derby victory to them. Throughout the 90 minutes, the Werkself had looked unfazed and in command, inflicting the first home defeat of the season on FC Köln. It was the sixth consecutive win against the Cologne team for Bayer 04 – head coach Carles Martínez, on the other hand, was facing the team from the neighbouring city for the first time and “now really knows what this derby win means”.
