Eintracht Frankfurt opened Bundesliga Matchday 6 with a much-needed 1-0 win against 1.FC Köln , following their 6-0 loss to RB Leipzig last weekend.

Saturday afternoon saw 10 teams in action, with Borussia Dortmund travelling to Union Berlin, Elversberg hosting Augsburg, Hamburg facing Stuttgart, Schalke playing Mainz, and Werder Bremen facing Paderborn.

Here are the three things we learnt:

Since Niko Kovac extended his contract at Dortmund earlier this week , they have not yet scored a goal. Obviously, this is purely coincidental, but what the loss against Bodo Glimt in midweek and this goalless draw against Union Berlin have shown is that Dortmund’s attack is underperforming.

The injury to Giannis Konstantelias and then Konstantinos Karetsas going off injured today don’t help, but the players who do make up die Schwarzgelben’s attack are clearly not able to generate the chances needed for Dortmund to score.

Ethan Nwaneri has struggled since joining the Bundesliga side on loan in the summer, but because of the lack of depth in the attack due to injuries, while Maximilian Beier is inconsistent, Matias Albert is 17, and Fabio Silva, after a hot start to the season, has seen a drop in his form.

On top of this, Kovac’s style of play is really hit or miss when it comes to whether it is even effective or not, and today has shown that it really isn’t, especially with the quality of players that he has at his disposal.

Something needs to change sooner rather than later, or Dortmund may end up regretting extending Kovac’s contract.

From a tactical formation and squad depth perspective, "Três coisas que aprendemos na sexta jornada da Bundesliga | O ataque vacilante do Dortmund, o impacto de Niclas Füllkrug no Bremen e um início de temporada louco" carries substantial tournament implications for international seeding and domestic campaign momentum. Coaching staffs are heavily weighing high-pressing efficiency (PPDA), defensive transition pace, and fixture fatigue management.

Tactical analysts monitoring Champions League metrics emphasize that squad adaptability and set-piece execution will likely dictate outcomes in high-leverage knockout environments. Real-time match telemetry and tracking data continue to inform managerial decision-making.
