Bayern Munich failed to win for a second consecutive Bundesliga game as they were held to a draw at Union Berlin.
After toiling for 75 minutes, Bayern appeared to have found the win to move them 11 points clear at the top through Leroy Sane.
But Benedict Hollerbach equalised eight minutes later to earn a point for Union and move them further clear of the relegation zone.
At the top of the German league, it means Bayer Leverkusen can close the gap with Bayern to six points if the reigning champions beat Stuttgart on Sunday evening.
Bayern took the lead when Michael Olise picked the lock with a clever pass in behind to Josip Stanisic.
Stanisic cut it back towards the penalty spot where Sane nipped in to finish.
After being shocked on their 125th anniversary by Bochum last weekend, Bayern appeared to have recovered as they knocked Leverkusen out of the Champions League in midweek.
But Vincent Kompany’s side suffered a setback as 21-year-old keeper Jonas Urbig – playing in just his third league game – spilled a cross, allowing Hollerbach to volley home.
The point moves Union seven points clear of the Bundesliga relegation play-off spot.
Meanwhile,RB Leipzig moved up to fifth place in the Bundesliga with a 2-0 win over Champions League quarter finalists Borussia Dortmund, who struck the woodwork three times in a pulsating second half.
Leipzig looked to be coasting after dominating the first 50 minutes and going ahead through goals by Xavi Simons and Lois Openda.
But Dortmund responded strongly, with Maximilian Beier hitting the bar and the post within five minutes of Leipzig’s second goal.
Karim Adeyemi’s shot was brilliantly tipped onto the crossbar by Leipzig goalkeeper Peter Gulasci, while Pascal Gross and Nico Schlotterbeck also missed chances to get Dortmund back into the game.
Openda had already hit the bar from close range when Leipzig took the lead, Simons latching on to a rebound from Dortmund keeper Gregor Kobel with a first-time shot from near the penalty spot.
Leipzig struck the woodwork again before half-time when Ridle Baku hit Dortmund’s bar from the edge of the penalty area, and they looked to taking total control when Openda volleyed in from a corner two minutes into the second half.
Dortmund, who qualified for the last eight of the Champions League with a 3-2 aggregate win over Lille, were stung into action but after spurning multiple chances they remain in 11th place in the Bundesliga.
Leipzig are one spot short of Eintracht Frankfurt, who played Bochum late yesterday, on goal difference.
