Third-tier Saarbruecken stunned Bundesliga champions Bayern Munich 2-1 with a last-gasp winner on Wednesday to dump them out of the German Cup in the second round.

Marcel Gaus netted the winner for the hosts deep into second-half stoppage time to complete a sensational comeback and trigger wild celebrations from the home crowd as the Bayern players looked on in complete shock.

Bayern, who last lifted the trophy in 2020, had taken a first-half lead through Thomas Mueller before Saarbruecken levelled in first-half added time.

“This is a brutal blow to us,” said Mueller, with his team next facing title rivals Borussia Dortmund in the Bundesliga on Saturday.

“To be eliminated for the third time in the second round of the Cup is not what we strive for. We have to congratulate Saarbruecken for their fight. A bit of luck is also part of it. Then we are hit on the break in the 96th minute but we had wasted too many chances before that.”

Bayern coach Thomas Tuchel made several changes to the team that crushed Darmstadt 98 8-0 on Saturday, leaving top scorer Harry Kane on the bench along with Kingsley Coman and Jamal Musiala while giving 20-year-old Frans Kraetzig his first start.

Bayern also had to take defender Matthias de Ligt off midway through the first half with the Dutch international suffering a knee injury.
