[3] Brøndby's chairman Jan Bech Andersen later said about Zorniger's dismissal, "If you can no longer change yourself and feel that you are compromising too much on your own way of leading people, it will end up in a bad place anyway.

[6][7] The team then traveled to Austria for a training camp, where they lost 3–2 to Ukraine's Shakhtar Donetsk on 26 June and drew 3–3 against CSKA Sofia a week later.

Brøndby's first Danish Superliga game of the season was away at Randers on 16 July; Schwäbe, Kaiser, Erceg, Uhre, and Kopplin all made their debuts.

This poor run of form saw Brøndby drop to a disappointing eighth place in the standings, with a seven-point gap to third-placed Esbjerg fB.

[18] During the winter transfer window, Uffe Bech, Larsson, and Kopplin left the club, while Simon Hedlund joined from Union Berlin.

[16] After a slow start to the spring season, with a draw against Nordsjælland and a loss to Esbjerg, popular head coach Alexander Zorniger departed.

Despite a strong record against Midtjylland, Brøndby fell behind early but rallied to win 2–1 with goals from Simon Hedlund and Jens Martin Gammelby, ending their four-game winless run, and adding three vital points to their tally.

To secure European qualification, they needed to win their final two league matches—a home game against Midtjylland and an away match against OB—while hoping OB would drop points.

OB's draw with Nordsjælland kept Brøndby's hopes alive, and a convincing 4–1 home victory over Midtjylland set up a decisive final match in Odense.

In the first match at the Rajko Mitić Stadium,[b] Brøndby secured a 2-0 victory, with Dominik Kaiser netting his first goal for the club just before halftime and Hany Mukhtar doubling the lead shortly after the break.

Although Brøndby dominated with their high press, they struggled to convert possession into clear chances, yet they managed the game effectively to secure the win.

Despite being reduced to ten men after Joel Kabongo's early red card, Dominik Kaiser put Brøndby ahead in the 68th minute.

Subotica equalised ten minutes before the end through Dejan Đenić, but Kamil Wilczek secured the victory with a stoppage-time goal.

Brøndby started the away match at Luminus Arena with manager Alexander Zorniger's characteristic aggressive pressing, but despite their efforts, they were unable to score early on.

Hany Mukhtar's long-range shot hit the crossbar, and his subsequent attempt was saved by Genk's goalkeeper, Danny Vukovic.

Mbwana Samatta added a fourth for Genk in the 87th minute, ending Brøndby's hopes of advancing to the Europa League group stage.
