The Manchester City star was a shock omission from Jogi Low’s squad announced on Monday morning.
Sane was a regular for the world champions as they breezed through qualifying, and featured in Saturday’s 2-1 defeat against Austria.
However, Low has dumped the 22-year-old PFA Young Player of the Year for the tournament in Russia, with Julian Draxler, Marco Reus and Julian Brandt preferred instead.
The German boss explained: “That was a very close decision between him and Julian Brandt, which was made in favor of Brandt. Draxler Reus and Müller are set. Leroy has a huge talent.
“He will be back again from September. He had not arrived in international matches yet. ”
Sane scored 14 goals last season as City stormed to the Premier League title.
