In cold and wet weather on and around the training ground at the BayArena, the Werkself squad returned after the winter break with the exception of long-term injuries Joel Pohjanpalo (rehab training after ankle injury) and Panos Retsos (rehab after muscle tendon injury to thigh) plus Leon Bailey and Charles Aránguiz (both for private reasons). At the same time, Marco Wolf, a 17-year-old forward with the club's U19 team trained with the pros for the first time.
An intense warm-up session was followed by a range of passing and shooting drills as well as a practice match at the end of the first session under the new Werkself coach Peter Bosz that lasted for just under one and three-quarter hours.
The Werkself carry on training on Saturday and Sunday (both at 10.30 CET) as well as on Monday (14.30 CET) in open sessions before the first friendly of the New Year on Tuesday (14.00 CET). The match against the Dutch first division club Twente Enschede will be played behind closed doors.
