Jogi Low watched the Man City winger play 67 anonymous minutes of Saturday's rain-sodden 2-1 defeat against Austria and has made a decision to axe him thereafter, as well as Jonathan Tah, Bernd Leno and Nils Petersen.
"There are better days in the life of a national team coach, when you have to send four incredible players, who deserve to be at the World Cup, home". Should they be victorious, Joachim Low's team would become the first since Brazil in 1962 to successfully retain the World Cup, and only the third in history after Italy also managed it in 1938.
His global form, however, is much poorer - he's only provided one assist and is yet to score following 12 appearances with the national side.
Sane has been given plenty of playing time of late - as much as can be expected with so few games in the months leading up to a World Cup - but he has not been able to show off his City form.
"I'm not anxious. I am no more a risk than any other player", Neuer said.
"Leroy has a huge talent and he'll be there again, and we'll have to work more with him again from September onwards".
Low explained it was a "very close decision" between Sane and Bayer Leverkusen's Julian Brant, who ultimately got the nod, adding that Sane, "has not arrived in worldwide matches yet".
"Julian Brandt had some good games at the Confederations Cup and was also very good in training, it was close".
"Low and team manager Oliver Bierhoff felt that the player would have done better to use the chance to stake his claim for the World Cup squad".
