Bayern Munich's six-game winning streak in all competitions was brought to an end as they drew 0-0 against Borussia Monchengladbach.
Bayern dominated the first half with David Alaba going closest but Gladbach, who confirmed their credentials as the Bavarians' nearest rival in the Bundesliga this season, responded well in the second half and arguably had the better chances to win it.
Lucien Favre's men were good value for their point at the Borussia Park Stadion, sending out a clear signal that the race for the title may not be as easy as Bayern may have thought.
It was a familiar sight for at least half an hour of the first half with Bayern dictating possession and penning Gladbach back in their own half.
Full-back Alaba went close to breaking the deadlock with a shot which Yann Sommer managed to touch onto the post with his fingertips in the 10th minute.
While being under such pressure may frighten many sides, Gladbach are of a different ilk. They thrive on it.
Having found their defensive shape, it was time for them to show what they could do on the counter-attack and Manuel Neuer was tested for the first time in the 34th minute.
It was a trademark break with Andre Hahn racing down the wing and sending the ball through for Max Kruse, who controlled it first time with his chest, but could not direct his shot powerfully enough past the Bayern goalkeeper.
Just before the break, Robert Lewandowski saw his shot deflect off the heel of Alvaro Dominguez and the ball spin just inches wide of the post.
Gladbach had only got their counter-attacking machine working once in the first half, but it seemed like they had spent the interval oiling it well as they emerged even stronger.
Kruse, Hahn and Raffael raced through in a three against two situation which saw Hahn's shot was parried out just inches away from the incoming Raffael.
A sweeping ball from deep found Patrick Herrman beyond Neuer, but the Germany number one stretched out an arm to turn the Gladbach winger's shot behind.
Neuer again stretched his frame to turn Raffael's free-kick behind before tipping another shot from the Brazilian past his post with the second half belonging to the hosts.
Rarely have Bayern been on the ropes so much in well over two years and they were perhaps more relieved than Gladbach to remain unbeaten, like their hosts, after 90 entertaining minutes.
