Borussia Dortmund's recent performances have revealed that their defensive display is not at the level required for a title challenge. The backline, which was stable in the previous season, has shown some unsettling weaknesses in recent matches that are concerning. In particular, the spatial organization and communication between the center-backs seem to be lacking the harmony they once had.

To address these issues, BVB coach Edin Terzić could make some tactical adjustments. One possibility would be to shift the defensive formation from a classic 4-2-3-1 to a more stable 3-4-3. This formation would not only strengthen the defense but also provide more control in midfield. The two wing-backs could operate as wingers, increasing pressure on the opponent’s defense, while the three center-backs would ensure better coverage in central defense.

Additionally, introducing a defensive midfielder who can operate between the lines could help alleviate pressure on the backline. Players like Mahmoud Dahoud or Axel Witsel could take on this role, and their intelligence and positioning could significantly contribute to the stability of the team. Their presence would allow the center-backs to engage more in offensive plays without compromising defensive security.

Another critical point is BVB's pressing strategy. In recent matches, the pressing has not been as effective, leading to dangerous counterattacks from opponents. A more targeted and better-coordinated pressing system could ensure that the ball is recovered earlier and that opponents are pressured before they can move into the offensive.

Ultimately, communication on the pitch is key. Defenders need to communicate clearly with one another and ensure they are better covered in critical situations. Regular team meetings during the training week could help improve this communication and develop a better understanding among players.

Overall, BVB requires a clear strategic direction to stabilize the defense. With the right adjustments, the club could not only strengthen its backline but also become more productive in attack, thus collecting the necessary points in the title race.
