Jonathan Tah and Co. split up into groups of three for the day working in the Werkstatt, the Bayer 04 rehab and training centre at the BayArena, on a range of tests and checks. That included taking blood and measuring body fat as well hip strength measurements plus different diagnostic procedures to test coordination, mobility and stability.





Before clocking off, the Werkself players underwent spiroergometry to finish off. Wearing respirator masks, the players were put through their paces as they clocked up as many miles as possible on the treadmill to test their stamina levels.






The squad led by head coach Xabi Alonso return to the training ground for the first time on Friday 2 December. The first session with the ball starts at 10.30 CET on training pitches 1 and 2. The Alonso team have a second training session in the afternoon at 14.30 CET.
Both sessions are open to Black and Red fans but last-minute changes are possible.

For the second time in four days, Bayer 04 face Borussia Dortmund this Tuesday evening, 2 December (kick-off: 21:00 CET) - this time in the round of 16 of the DFB Pokal, with more than 7,000 fans supporting the Werkself at Signal Iduna Park. After the recent 2-1 defeat to BVB in the league, several cup stats provide hope of revenge for the Black and Reds. There are several reasons why Bayer 04 recommends getting to the round of 16 clash early, in which VAR will be in use, unlike in the previous rounds.
