Kovac initially stuck with the 4-2-3-1 system used by his predecessor when he took charge of the first-team in January, but a poor run of four defeats in six games, including a heavy 4-0 loss to Barcelona, forced him to rethink. He then switched to a 3-4-2-1 formation later in the season, a change that became a turning point for his side. Since then, Dortmund have climbed into the top four for the 2024-25 season and have remained unbeaten in both the Bundesliga and the Champions League across last season and this season.
