German NT will start practice on 21 April but mostly with U23 players, the experienced players get some rest after club team season and will join the team 10 days later. The younger players will play friendly matches with French NT from 1-3 May in France. After that the "young" and the "old" players practise together in Kienbaum to prepare for VNL and will play 3 friendly matches (opponent TBA) in Schwerin from 14-16 May.
There will also once again be an extra U23 NT coached by Alex Waibl which will participate in Universiade in order to provide more experience for young talents.
In total 29 players are invited for the summer: (potential U23 players in italic)
Setter: Corinna Glaab, Sarah Straube, Pia Kästner, Magdalena Gryka, Denise Imoudu
OPP: Kimberly Drewniok, Luisa Keller (also OH), Marie Hänle. Liza Kastrup, Louisa Lippmann
OH: Lina Alsmeier, Emma Cyris, Jennifer Janiska (Geerties), Ivana Vanjak, Hanna Orthmann, Jana-Franziska Poll, Lena Stigrot, Pia Leweling, Vanessa Agbortabi
MB: Anastasia Cekulaev, Lea Ambrosius, Marie Schölzel, Josepha Bock, Camilla Weitzel
Libero: Elisa Lohmann, Linda Bock, Simona Dammer, Sophie Dreblow, Anna Pogany
The only name I'm missing in the list is Anne Hölzig as OH but looking at who was invited I'm sure she would be there if she wanted, so probably she declined the invitation. I remember reading in some article from Straubing that she was focusing more on her studies during last season so maybe she'll finish that during summer.
MB position is a problem because there is no serious backup for Schölzel and Weitzel. Bock and Ambrosius are talented players but still far from international level and Cekulaev is considered as one of the biggest young talents in Germany overall but so far she has only played in 2nd league.
