After three consecutive Bundesliga draws, Bayern was looking to get back on track in Saturday's Bavarian derby, but a 1-0 loss has compounded the team's domestic troubles.

It was only a first league loss of the season, but Bayern has now gone four games without winning in the competition, and the team that last season clinched a 10th consecutive title is in a mini-crisis.

It remains to be seen whether it escalates beyond that, or whether Nagelsmann succeeds in getting the team back to form, but Salihamidzic tellingly questioned the performance as much as the result.

His verdict was that Bayern "can't win in the Bundesliga like that", urging the team to show "discipline, greed and physicality", clearly suggesting it was lacking in each area.

Salihamidzic said: "We didn't finish the situations, several situations that we had, didn't finish in a concentrated manner, didn't play through to the end with a certain greed of wanting to score goals; and we also allowed a few chances against us, didn't defend those situations to the end, and we can't win in the Bundesliga like that."

Salihamidzic, a former Bayern player, said the current side are showing they have "brutal problems against teams that play against us physically, that knock our socks off, so to speak".

There has been no suggestion yet from Bayern that Nagelsmann's position is under threat, with early UEFA Champions League group wins against Inter Milan and Barcelona surely helping his cause in that respect.

But he is facing scrutiny from outside the club, and the results in Germany's top flight are plainly causing unease in the Bayern hierarchy.

"If we don't bring that certain discipline, greed and physicality, then you can't win in the Bundesliga," Salihamidzic said. "Now there are no more excuses. Now we need wins."

Nagelsmann, the former RB Leipzig boss, who is in his second season with Bayern, lost star striker Robert Lewandowski to Barcelona in the close season.

Lewandowski's de facto replacement, Sadio Mane, has managed five goals in 11 games across all competitions but has not found the net in his past five appearances.

As a collective, Bayern is not performing to its usual standard in the Bundesliga, and it falls to Nagelsmann to stop the rot.

Bayern's run of scoring in 87 consecutive Bundesliga games has been halted, and the coach has the international break in which to figure out what is so wrong.

Speaking after the final whistle in Augsburg, Nagelsmann said he was "thinking... about the situation, about myself, about everything".
