This season has shown that Arminia Bielefeld struggles to break through opponents' defenses in attack. Despite a solid defense that is often well organized, the team lacks the necessary cutting edge in front of goal. A change in formation could benefit the team, allowing them to improve midfield play and utilize wing players more effectively.

A 4-3-3 system could be advantageous here. By incorporating a central playmaker who pulls the strings in midfield, the team could not only develop more creativity but also set wing players up for success. Players like Andreas Voglsammer and Nathan de Medina could be sent through on goal with targeted passes to outsmart opposing defenses.

Additionally, it would be wise to increase pressure on the opponent's backline. An aggressive pressing approach in the opposition's third could lead to Arminia Bielefeld winning more possession and thus creating more dangerous chances. Players like Masaya Okugawa could play a key role in this by pressuring defenders and winning the ball back.

Another aspect that needs addressing is set pieces. Here, Arminia could benefit from a focused training week to be better prepared both offensively and defensively. The strategic use of corners and free kicks should be planned to exploit the physical presence of players in the box.

Finally, improving communication on the pitch is crucial. Open dialogue among players can help avoid misunderstandings and optimize coordination in gameplay. By fostering teamwork and a better understanding of each other's roles, Arminia Bielefeld can lay the groundwork for a successful second half of the season.

In summary, through targeted tactical adjustments in attack, increased pressing, and better utilization of set pieces, Arminia Bielefeld can significantly improve their form. Moreover, communication on the pitch should not be overlooked to enhance team dynamics.
