Tenhach has begun to lead Leverkusen for summer preparation training, and German media Biography has included some of his differences with former coach Alonso's training, as well as his special methods of using drones to record videos in training. The report said that in the first few days of Tenhach, he allowed the team to train on the court for nearly two hours, and before the training began, professional and youth players warmed up at the speed training ground in the Bayer Arena player area.

Bodiac pointed out that during the coaching period of former coach Xavi Alonso, training classes on the grass rarely exceeded 75 minutes. A striking feature besides the training duration is that during the entire training process of Tenghach, there was always a drone hovering over the court, shooting the training content from a overlooked angle.

It is reported that a camera system is installed on the training ground in Leverkusen, which can also provide similar overhead shots. During Alonso's coaching period, he also used drones, but not as thorough and continuous as Tenghach is now.

These drones recorded images can be displayed directly to the players on the field, and for this purpose they installed a video display in a small transport vehicle. Like Alonso, Tenghach also uses more game formats to train passes and runs – but he has introduced new elements on this basis.

midfielder Hoffman said: "The coach said he wanted to continue to develop on the basis of Alonso's work over the past two years. But he certainly had his own ideas. We are trying to adapt to the basic principles he has stated and proposed very clearly as soon as possible."

In these forms of training, there is a special point: Tenhach doesn't seem to like passing the ball with his heel. If a player lets the ball pass between his legs and then passes the ball with the heels that support the leg, it will be immediately considered a loss of the ball. In other words: Heel passes are prohibited.

In small court games, Tenghah asked three teams to conduct offensive and defensive training at the same time. The goal is: fast, stress-suggested passes, and a high concentration.

A new rule is that after each round of training, the players of the losing team must do ten push-ups, which increases the players' desire and fun to win.
