The U16 team will be playing a 3-Nation-Tournament with Switzerland and Austria in Füssen starting on Thursday.
I don't think there will be any live stream.
I may have been wrong about this.
There also seems to be another game scheduled for today vs. Switzerland and it as well as the tournament games starting tomorrow appear to be on soccerwatch.tv
Germany vs. Switzerland - 08/24/2022 - 18:30 CET - Stream
Germany vs. Switzerland - 08/25/2022 - 17:00 CET - Stream
Switzerland vs. Austria - 08/26/2022 - 15:00 CET - Stream
Austria vs. Germany - 08/27/2022 - 11:00 CET - Stream
The streams will likely be without commentary and the camera is probably automated.
