According to Biography, Leverkusen's new coach Ten Hach has given up his favorite four-defender tactics in training.

During Tenghach's coaching career, he has always preferred to use the 4-3-3 or 4-2-3-1 formation. However, Tenghach decided to replicate the 3-back formation used by Alonso in the next game

, previously led by Alonso, Leverkusen used a 3-4-2-1 formation as the main formation and won the double championship in 2024.

It is reported that the main reason why Tenghach chose to use 3 defenders is: if he wants to use 4 defenders, he needs to introduce a winger and make a larger lineup adjustment. However, this summer, the team has lost core players such as Wilz, Ta, and Zachar. Too many changes may bring too much uncertainty to his performance on the court.

Leverkusen sports director Rollfers said in an interview with Biography: "I believe this is a good system. Our system is very stable, and we have players that match it."

It is reported that Leverkusen is currently looking for a fifth central defender. This is obviously beneficial to the three-back formation. "I'm more inclined to form a lineup that can use both three and four defenders to increase the diversity of the lineup," Tenghach said.
