Borussia Dortmund rolled into Munich two days after the 40th anniversary of the "Rumble in the Jungle," and there were a few parallels between the match and the bout that is considered one of the greatest ever in boxing.

Dortmund, lying in the relegation zone, were cast in the role of Muhammed Ali, the former champions who had seen better days.

Bayern played the part of George Foreman, the seemingly unbeatable heavy hitter.

And the hosts got in the better of the early blows, with Arjen Robben and Thomas Müller creating a number of good looks.

Like Ali, though, Dortmund caught them on the chin midway through the first-half. Pierre-Emerick Aubameyang sprinted down the right-hand side and delivered an inch-perfect cross that split Bayern's central defense for Marco Reus to head the visitors in-front.

Bayern had twelve shots on goal to Dortmund's five, but Jürgen Klopp's men took the lead into the interval. Dortmund keeper Roman Weidenfeller was in outstanding form, even as Munich tied down their adversaries in their own half after the restart.

But Neven Subotic, brought on as a half-time substitution for injured Mats Hummels, failed to get a solid foot to an attempted clearance in the 72nd minute. Former Dortmund striker Robert Lewandowski curled a low shot past Weidenfeller to level the match.

Subotic was again the negative center of attention when he brought down Franck Ribery in the area five minutes from time.

Robben, who had missed a number of key penalties against Dortmund three seasons ago, stepped up to the spot and slammed the ball home to bag the three points for the league-leaders.

"We played too little football in the second half," Jürgen Klopp said after the final whistle. "The pressure was too much. In part we gave the game away."

Hamburg beat Leverkusen

Hakan Calhanoglu's return to Hamburg will be one he'll want to banish from memory, as his former side got one over on him with a 1-0 win.

The 20-year-old's first match back in the city after a thorny move to Bayer Leverkusen during the summer transfer window was scrappy and confrontational. The half-time whistle was blown amidst a 22-man brawl on the side of the pitch.

But Hamburg's progress under new coach Josef Zinnbauer continues. The lone goal of the afternoon arrived from the penalty spot in the 26th minute. Rafael Van der Vaart stepped up and dispatched the spot-kick to send the home side into the lead.

Following several players' attempts to calm the raging home support when Calhanoglu ventured near to the touchlines, the men on the field completely lost their discipline on the half-time whistle. An unnecessary challenge from Giulio Donati sparked a rammy in the middle of the park, which involved some of the coaching staff of either side.

Given Hamburg's perilous position at the bottom, the three points were crucial. It meant that Borussia Dortmund, at least temporarily, dropped into the relegation zone before their match with Bayern Munich this evening.

Bremen back?

Viktor Skripnik managed to pick up Werder Bremen's first league win of the season, as his side come from a goal behind to take the 2-1 victory in Mainz. After a controversial penalty to level, Skripnik could thank Franco di Santo for a brilliant chip to secure the three points.

Mainz were ahead within three minutes: Shinji Okazaki scoring as Werder Bremen's defense remained in disarray. The home side battled on and controlled more of the possession, but lacked the quality to penetrate Werder's defense.

Against the run of play, Werder's Fin Bartels went down under pressure from keeper Loris Karius and was given a spot-kick. Argentine Di Santo missed the first attempt - Karius saving - but headed in the rebound.

And Werder's top scorer this season Di Santo stole the winner, latching on to Felix Kroos' pass, killing the ball sweetly, before looping the ball into the top corner.

Wolfsburg march on

Elsewhere, Wolfsburg convincingly consolidated their spot in the top three, leaving Stuttgart with a 4-0 win in the bag.

The scoring started with a lung-bursting run and finish from Ivan Perisic. Robin Knoche netted late in the first half, before Vieirinha set up Kevin de Bruyne to round off a rip-roaring counterattack from the Wovles. De Bruyne assisted Perisic in the final few minutes to add some shine to the scoreline.

Meanwhile, Alexander Madlung's 88th minute own goal handed Hannover three points against Eintracht Frankfurt, moving them into contention for a spot in Europe.
