We know that now. That was not evident to me before he was dropped. I hadn't realised he was struggling in the German squad.
This must be a rational decision by the coach which is a little bit worrying as it suggests Sane has some weakness.
No it doesn't. It suggests he has some weaknesses in a lesser squad with a lesser manager playing in a different style and system. There's about 18 of that 23 that would get nowhere near our side.
Brandt, Kimmich, Neuer, Gundogan & Kroos for me would make our squad. Muller a few years ago.
