Bayern Munich and Borussia Dortmund have both started the 2015/16 season in outstanding fashion. The defending champions lead the way with seven wins from seven, as BVB's two draws over the last two matchdays leaves them four points back. A loss this weekend could spell the end of any title challenge for Thomas Tuchel and his team, but with five wins in their last ten meetings, BVB is hopeful.

Dortmund's Andreas Möller was a controversial character on the pitch - sometimes brilliant with the ball at his feet, sometimes crude in his play acting. Back in 1997, Bayern's Lothar Matthäus lost his cool amid Möller's antics, angrily calling him a crybaby on the pitch. The insult got under Möller's skin and in response he put his hand in his Germany teammate's face. The match ended 1-1.

Oliver Kahn was running on adrenalin back in 1999 when he tried to clear a path in front of Dortmund player Stephane Chapuisat. Despite his flying kung-fu kick, the Bayern goalie just missed the Swiss striker. Still, it's one of the most famous sporting photos in German football, and reveals the passion involved in this fixture.

This was a game that got everyone talking. In April 2001, Dortmund and Bayern played what was meant to be a football game but turned into a foul-fest. Three people were sent off and 13 yellow cards were handed out as referee Hartmut Strampe was the busiest man on the pitch in a game that ended in a draw.

Not a bad start: In the battle for honor in this year's German Super Cup, Dortmund come out on top, winning 2-0 at Signal Iduna Park. Mkhitaryan and Aubameyang were on the scoresheet and only Manuel Neuer prevented Bayern from conceding less. It was an early statement of intent fromBVB, one they have not been able to follow up since.

All left-foot. All composure. All encapsulating the exuberance of Jürgen Klopp's Dortmund in the 2010/11 season. Having beaten Bayern at home, Nuri Sahin set the stage alight in the 17th minute in Munich. After several deft left-foot touches to secure possession, Sahin instinctively bent the ball deliciously around the defenders and into the far corner of the net to aid BVB to a 3-1 away win.

In 2012, Dortmund managed perhaps their most resounding win against their Bavarian rivals. In the cup final in Berlin they triumphed 5-2 - just weeks after succesfully defending the Bundesliga title. Many spoke of a changing of the guard in German football. If anything, the defeat merely galvanized Bayern, who went on the offensive in terms of titles and transfers- even acquiring some BVB players.

On their way to a stellar year in 2013, Bayern had a crucial quarter-final win against Dortmund in the German Cup. The difference that night was Arjen Robben. The Dutchman scored the only goal of the game, a screamer from distance, and proved a constant problem for Dortmund's defense.

The Bundesliga title soon followed for Bayern, but it was the game afterwards that is perhaps the most important match-up between the two sides: The 2013 Champions League at Wembley. Bayern won 2-1 after a goal from who else but Arjen Robben. It's fair to say it was the biggest win in the recent history of Germany's most successful club, and was considered one of the best finals in recent years.

Bayern hadn't forgotten. In April 2012, Neven Subotic mocked Arjen Robben for his missed spot-kick in the last few minutes in a game Dortmund won 1-0. In the Champions League final, Bayern's players took the opportunity to rub the 89th minute winner from Robben right in Subotic's face.

Hours before Dortmund faced Real Madrid in the Champions League semi-finals, Bayern Munich confirmed the signing of Mario Götze. He'd return to Dortmund around four months later and received an unpleasant reception. But the 22-year-old was unmoved, scoring the crucial opener to set Bayern on their way to another three points.

Tensions reached simmering point in a seemingly meaningless end-of-season league encounter in 2013. Jürgen Klopp and Matthias Sammer, Bayern's sporting director, clashed on the touchline, as tempers frayed on either side. This incident, in a microcosm, has set the tone for Bayern-Dortmund relations ever since.

When Klopp isn't squaring up to Sammer, duels are being served between the head honchos at the top: Karl-Heinz Rummenigge and Hans-Joachim Watzke. Rummenigge's incessant pursuit of Marco Reus up until this season, via comments in the media, has been a cause for annoyance among Dortmund fans and executives.

For years Robert Lewandowski wore the yellow and black of Dortmund. Then, last summer, the Pole moved to Bayern. In his first league game against BVB, Lewandowski scored against his old club, helping Bayern to a 2-1 win. Lewandowski scored again as Bayern beat Dortmund 1-0 at the Signal Iduna Park. He now has three goals against his former side having scored in the German Cup semifinal defeat,

In an encapsulating German Cup semifinal Jürgen Klopp's Borussia Dortmund overcame Bayern Munich on penalties at the Allianz Arena. Pierre-Emerick Aubameyang cancelled out Robert Lewandowski's first half strike in normal time before Philipp Lahm and Xabi Alonso slipped in the shoot-out. With Bayern missing their four penalties, one last Der Klassiker victory for Klopp clinched a final place.
