In addition to the internal and orthopaedic tests, that were carried out in part on Monday, 17 players (split into groups of three) and excluding the international players, completed a range of tests on strength, coordination, movement, balance, acceleration and stamina. "With the help of the data, we produce an individual profile for each player to see exactly where the particular strengths, weaknesses or performance limiting factors are," explained Malte Krüger, the head sports scientist at Bayer 04. The data acquired primarily serves to optimise the training programme over the course of the pre-season. "That means the players can work in a targeted and individual way with our fitness coaches Schahriar Bigdeli, Terry Peters and Daniel Jouvin to endeavour to make up deficits or to reduce the risk of injury – without the daily training on the pitch having to suffer," added Krüger.
Of course, the aim is to be as well prepared as possible for the three competitions facing the Werkself of the Bundesliga, the Champions League and the DFB Cup. "We want to keep all players fit and healthy through the season and make sure they are fully fit when the busy weeks start," said Krüger.
















Kai Havertz, Lukas Hradecky, Aleksandar Dragovic, Tin Jedvaj and Paulinho, who were given extra leave due to their international appearances at the beginning of June, will complete the performance tests on Sunday.

Sandwiched between their UEFA Champions League knockout play-off tie against Olympiacos, Bayer 04 return to Bundesliga action on Saturday with a trip to Union Berlin (kick-off: 15:30 CET). It’s a fixture of contrasting styles, with Leverkusen preferring to control the play while Union look to remain compact and counter. The Berliners are therefore suited to facing top teams, but they have only ever managed to win one of 16 meetings with the Werkself, who are looking for a fifth clean sheet of 2026 but will need to beware the home side’s threat from set pieces. Here’s all you need to know ahead of the game in our matchday news.

It took exactly 60 minutes for the Werkself to take the lead through a perfectly finished counter-attack by Patrik Schick in the first leg of the 2025/26 UEFA Champions League play-off at Olympiacos. Referring to the meeting in the league phase and the initially squandered opportunities, coach Kasper Hjulmand said afterwards: "I thought: 'Oh no, déjà-vu.'" But after the opening goal, it took just 144 seconds for the Czech to spark more wild celebrations among those in black and red in the Greek cauldron, when Schick nodded in Alejandro Grimaldo's corner. Much to the delight of the Bayer 04 fans, his teammates and his coach, who had warm words for the striker in the aftermath. The Werkself Review.
