Kerem, after winning four league games in succession, you suffered the first reverse of the year in the 3-2 defeat at Mainz at Mainz last weekend. How have you dealt with that in terms of analysis and training?
Demirbay: It was clear to us from the start that Mainz would be defensive and aggressive. Unfortunately, we didn't succeed in being equal to or better than Mainz in certain areas – for example in relation to aggression and resolution. We also didn't make enough of our quality. So you have to say they were better than us on the day.
As in the overall table, you are currently third in the second half of the season table. What's your assessment of the previous performances and displays in 2022? In what areas have you made progress compared with the first half of the season?
Demirbay: In many. One important point is that we don't fall apart after going behind or conceding goals but instead remain disciplined in pursuing our approach and playing our game. That didn't always happen in the first half of the season. On top of that, we have become much more aggressive and our game is more intense – both with and without the ball. Those are all certain nuances that make a big difference overall.
How important is communication on and off the pitch during these phases?
Demirbay: Communication over the full 90 minutes is the name of the game as it can keep a team going. It enables you to gain energy yourself or to give your teammates a lift. We have certain players who lead the way in communication. But it's also a responsibility for all of us to a certain extent.
This season you’ve become an absolute first choice. What's your assessment of your performances in the current campaign to date?
Demirbay: On the one hand, I've developed personally off the pitch. In terms of football, I have become more consistent with my performances. I really feel at home here, I’m growing with the team and have a role at this club that I'm really into and it gives me an incredible amount of energy game after game.
What influence has the coach Gerardo Seoane had on you and your development?
Demirbay: He gives me a lot of confidence and freedom but I know in return what he can ask of me and what he gets. He demands a lot from all of us. Not too much – that's a difference.
The Swiss boss again and again emphasises he feels happiest with two holding players in midfield. What instructions does he give you for that position? What do you have to look out for?
Demirbay: We have to be players, fighters and tacticians in midfield and create balance in our own game. In certain situations we can make the difference in this position. We have to help the defence so they can easily play out from the back but also be able to win second balls. Basically, it's important that at least one holding midfielder maintains his position in every situation in the game. If one gets involved in attacking or as part of aggressive counter pressing then the other drops back. That gives us more stability.
At the moment, you're playing in holding midfield alongside Robert Andrich who arrived from Union Berlin last summer. What's special about your interaction?
Demirbay: We understand each other well on a personal level and are on the same wavelength. I really value his direct approach as a Berliner. But I'm also very happy I'm not his opponent. He can be very tough on the pitch. His defensive work and stability is an addition to my more attacking style of play. But we can both do the two things. Communication on the pitch is very good and that obviously makes our job even easier.
Just like Rob, you create the impression of being able to stand up physically in spite of your outstanding technical abilities. And then it appears to be of secondary importance if an opponent is over 1.90 metres tall like Moussa Niakhaté at Mainz 05. How important is aggression to your game?
Demirbay: It definitely is part of my game. It doesn't always have to be about a sliding tackle as it's also possible with anticipation, chasing or getting the ball away from the opponent. And those are the reasons the club brought me here back then. If I find out that my teammates, who are also my friends, are being mistreated by opponents then I'm not afraid of getting involved.
Saturday brings the home match against Arminia Bielefeld. What will be crucial in that game?
Demirbay: Basically, the same things as in the game against Mainz. They definitely won't give anything away, we have to focus in preparation for this opponent and we can't afford to underestimate them. We'll only win if we can master the basics. Aggression, intensity, ambition, communication – from the first minute they'll have to realise there's nothing doing for them here.
Based on the coronavirus protection order from the state of North Rhine-Westphalia, 10,000 fans can come to the BayArena and it appears that full capacities at stadiums will be possible again from April. How important is a proper stage at home matches for achieving this season's targets?
Demirbay: Very important. Everybody cheers when you’re leading 4-0. But if it gets tight, the scores are level or if we are behind then the fans are incredibly important. They can help us win games with their support if they get behind us and get us going again and give us strength even if we are tired. We need our fans to help us achieve our targets.

Standing on the pitch where the Werkself players perform - for many Bayer 04 club members, this wish became reality at this year's Members' kickabout. Around 400 active participants of all ages took the opportunity to experience the BayArena from a new and special perspective. And there was also plenty going on in the stands: The event attracted more than 1,000 visitors in total and provided an atmospheric end to the season.

Lying third in the Bundesliga, the Werkself made a faltering start in 2026 after the winter break, but gradually rediscovered winning ways and, as in the previous campaign, were among the top 16 in Europe and the top four in the DFB Pokal. In the Bundesliga, the Werkself also remained in the race for Champions League qualification right to the end. However, because setbacks repeatedly crept into the Werkself's performances between good displays and crucial games, it was not quite enough to secure a UCL spot in the end. A season with many ups and downs brought sixth place and qualification for the UEFA Europa League. Part II of the review of the 2025/26 season.

Following the final match of the 2025/26 season, the prevailing feeling was naturally one of disappointment after missing out on qualification for the Champions League. The Werkself finished the Bundesliga in sixth place, meaning they'll start the 2026/27 campaign in the Europa League. "But to talk negatively about everything now because of that would be wrong," stressed captain Robert Andrich following the final game, knowing that the past year at Bayer 04 was marked, more than almost any other, by the start of a new era and the courage to change – and in particular, the belief in a positive direction. Everyone was aware this process would need time. The first part of the 2025/26 season review.
