It's so annoying how Heynen simply can't use the potential of this team Even with this messed up line-up they manage to make the game close. Just use Drewniok as OPP and either let Orthmann receive or play with two of Geerties/Alsmeier/Emonts as OHs and things probably would look better for German team.
it's not like Drewniok is a powerhouse in attack, Orthmann is IMO better offensively and they are really playing good, Serbia is just too strong
but yeah, after 2 lost sets maybe he should give this lineup with Drewniok a try
