Germany are set to be the defending champions as 2018 FIFA World Cup begins in Russian Federation on June 14 but they have had a very shaky preparation going into the tournament. In this phase we were careless and in the second half we could not turn it around anymore.
Even as Austria scored just two goals, they could have scored more and constantly threatened Germany in front of their home supporters.
The game changed after half time however, as Austria pressed Germany more and more.
Although boss Low was heartened by the return to action of goalkeeper Manuel Neuer, he was unable to mask how dispirited he was by his side's display.
Forward Nils Petersen was given his Germany debut at the age of 29 but was largely anonymous.
"It was a good comeback from Manuel after so long out", Loew told broadcaster ZDF. "He had no problem with his injury".
"On Monday morning, I will speak to the relevant players and they will leave the squad around midday", said Loew. We lost the ball unbelievably often, there were so many turnovers.
Despite missing 259 days with a fractured foot, Neuer looked sharp but Loew says he will see how his goalkeeper's problematic left foot reacts on Sunday.
"They will demand a lot from us".
Austria started to find their feet around the half hour mark and some patient build up play created a chance for Peter Zulj but he shot straight at Neuer, who shortly afterwards made a superb save to push away a strike from Florian Grillitsch after he had tried to catch out the goalkeeper at his near post.
Germany then fell behind in the 69th minute when Stefan Lainer lifted the ball over the back four and found Alessandro Schöpf, who made no mistake from close range.
Loew last coached at club level in 2004, when he was at Austrian Vienna, and under his stewardship Germany has reached at least the semi-finals of every global tournament since the 2006 World Cup.
