The goalkeepers Lennart Grill and Niklas Lomb plus homegrown player Emrehan Gedikli formed the first group of three at the performance tests at the BayArena on Monday morning. Another 13 senior players plus seven youth players followed over the course of the day. There were the usual warm greetings after the summer break with everybody in a buoyant mood and full of anticipation ahead of the forthcoming tasks.
Anticipation ahead of the performance tests was kept within bounds as Dr. Malte Krüger knows from previous years. “We are aware this day is not necessarily the most popular. (He laughs) It is a real workout as the tests last longer than a normal training day,” said the head sports scientist at Bayer 04. “But the players know the importance of this day and they see we gain important knowledge that relates to their physical condition and also benefits them and their health and fitness in the pre-season.”
Dr. Krüger also explained why he believes the performance tests have to be completed before the first session on the training ground. The 39-year-old: “On the one hand, the players come here after several weeks of individual preparation, on the other we want to identify possible deficits before the dynamic sessions on the pitch instead of afterwards.”
The Werkself players went through ten different tests in succession on Monday with the whole procedure lasting three hours for each player. Nadiem Amiri and Co. spent two thirds of the time with medical checks. They are partly prescribed by the German Football League (DFL) with Bayer 04 also carrying out additional tests. The checks include organ tests, sight tests, a dental examination, an ECG plus neurological investigations.
The traditional performance tests followed. On top of that there are strength tests on hip muscles, flexibility tests and stamina diagnostic tests – the so-called spiroergometry on a treadmill. “Players are tested to the limit without pain,” said Dr. Krüger. The tempo is increased in a five-minute rhythm with some players covering a distance of more than six kilometres at a speed of 20 kmph.
To deal with the majority of the tests on one day, several external experts are involved including the German Sports University (Spoho) in Cologne, and Bayer 04 have worked with them on the performance tests for several years.
Working with the club’s sports scientists, team doctors, fitness coaches and physiotherapists, the tests can provide basic conclusions for course of the season. “The investigations we complete each year are obviously very comprehensive and involved. But we gain important knowledge that enables us to assess the players’ development, reveal deficits and do preventive work.”

Bayer 04 put in a brilliant performance to beat RB Leipzig 4-1 on Bundesliga matchday 32 and are now fourth in a Champions League spot. The Black and Reds took control of the game right from the start and, with 75 per cent possession at one stage, took a 2-0 lead into the break through Patrik Schick (25’) and Nathan Tella (45+1’). The visitors initially tried to do more after the break, but the Werkself remained determined and Schick scored his second goal to increase the lead to 3-0 (76'). The Red Bulls pulled a goal back through Christoph Baumgartner (80'), but the disciplined Leverkusen side were not rattled - and certainly not Schick: The Czechia international crowned a brilliant display with his third goal shortly before the final whistle to make the final score 4-1.

In the previous game against RB Leipzig in December last year, the Werkself turned came from behind to win 3-1 and further improved Leverkusen's already strong record against the Red Bulls. Montrell Culbreath stood out with his first goal on his debut for the Black and Reds. While the 18-year-old would certainly like to score a second goal against Leipzig on Saturday night, the attack-minded visitors come to the BayArena in confident mood after five Bundesliga victories in a row. The Nordkurve12 supporters group knows the Werkself will therefore once again be reliant on the vociferous support of the fans, and has once again called for the ‘Finally Red’ campaign in the run-in. Today’s matchday news.
