DVV president just said in a TV interview that Felix Koslowski will be NT coach this year as well, but it sounded like it might not be a long-term solution. DVV will first look for a successor for Vital Heynen in men NT and after that they will focus on women NT
There hasn't been much info about players except for Ssuschke and Beier retiring from NT, and I guess Fürst won't be back either. Some others might take a summer off this year, but there have been no official news yet.
Here is my selection of players who I think could be invited for NT (new players in italic
S: Mareen Apitz, Denise Hanke, Denise Imoudu, Lena Möllers, Mareike Hindriksen, Irina Kemmsies - I think Weiss is not needed anymore, time to give a chance to the youngsters
OPP: Margareta Kozuch, Louisa Lippmann, Saskia Hippe, Kimberly Drewniok, Hanna Orthmann (also OH)
OH: Maren Brinker, Jennifer Geerties, Lisa Izquierdo, Laura Weihenmaier, Jana Franziska Poll, Lena Stigrot, Tanja Großer, Katharina Schwabe, Sina Fuchs, Dora Grozer
MB: Anja Brandt, Wiebke Silge, Jennifer Pettke, Marie Schölzel, Leonie Schwertmann, Barbara Wezorke, Rebecca Schäperklaus, Lisa Gründing
L: Lenka Dürr, Lisa Thomsen, Janine Völker, Anna Pogany, Claire Bertram, Michaela Bertalanitsch
Probably some of the players won't be invited, but I think this year is the time to try as many players as possible and see who can help NT in the future.
