European champions Bayern Munich went top of the Bundesliga for the first time this season on Saturday after a pulsating 1-1 draw at Bayer Leverkusen.
Bayern extended their unbeaten run to 33 Bundesliga games and are closing in on Hamburg's record of 36, set in January 1983, as the Bavarians faced the team who defeated them at home in October 2012.
Previous leaders Borussia Dortmund lost top place after suffering a shock 2-0 defeat at Borussia Monchengladbach earlier in the day.
In a high-tempo clash at Leverkusen's BayArena, Germany midfielder Sidney Sam's 31st-minute equaliser for the hosts came straight after Toni Kroos' opening goal for Bayern.
Pep Guardiola's Bayern took the lead when France winger Franck Ribery found Kroos on the edge of the area and the attacking midfielder blasted home.
But Leverkusen drew level when Germany goalkeeper Manuel Neuer parried Poland defender Sebastian Boenisch's shot, but the rebound fell to Sam to tap home into an empty net.
Bayern, fresh from Wednesday's 3-1 UEFA Champions League win at Manchester City, again dominated possession -- nearly 80 per cent -- but were continually frustrated by some determined defending.
Leverkusen goalkeeper Bernd Leno was determined to earn a point for his side as he denied Ribery twice in as many second-half minutes.
Germany midfielder Bastian Schweinsteiger had a late header cleared off the line, while Leverkusen's Son Heung-Min blasted wide with the final shot of the game.
The single point was enough to send Bayern top, with Leverkusen third, behind Borussia Dortmund.
'Gladbach hand Dortmund first loss
Fresh from their impressive 3-0 Champions League win over Marseille, Dortmund were set to claim an away point until a disastrous final ten-minute spell.
Germany defender Mats Hummels earned a red-card on 81 minutes with a reckless challenge on 'Gladbach's Norway midfielder Havard Nordtveit in the area which left referee Manuel Graefe reaching for the red card.
Germany striker Max Kruse netted the resulting penalty, then Brazilian forward Raffael struck four minutes from time to see 'Gladbach move up to fourth.
"That was an unusual game, we had our opponents under brutal pressure for long periods of play, but didn't score," admitted Dortmund coach Jurgen Klopp.
"We played our part in the defeat, we left the game too open and allowed 'Gladbach to come to life when they took their chances."
Dortmund dropped to second in the league, a point behind Bayern, and level on 19 points with third-placed Leverkusen.
Dortmund midfielder Sven Bender is an injury doubt for Germany's FIFA World Cup™ qualifiers against Republic of Ireland on Friday and Sweden four days later after being left bruised by a second-half challenge.
Schalke fight back, Braunschweig upset Wolfsburg
Schalke came from behind to claim a 4-1 win over ten-man Augsburg in Gelsenkirchen to move up to eighth.
Stuttgart dropped to seventh after their 1-1 draw at home to Werder Bremen while Hoffenheim, who narrowly avoided relegation last season, stayed tenth with a 2-2 draw at Mainz.
Eintracht Braunschweig, who had spent the season thus far bottom of the table since last season's promotion, picked up their first win of the season with a shock 2-0 victory at Wolfsburg -- their first Bundesliga victory since 1985.
Midfielder Karim Bellarabi scored the opening goal after 30 minutes before Congo forward Domi Kumbela put the result beyond doubt with a late second.
The win lifted Braunschweig off bottom place with Freiburg, who host Frankfurt on Sunday, dropping down to last place.
