Cologne - FC Bayern München appear to be simply unstoppable at present, as their performance in Der Klassiker on Sunday underlined.

Even with a big lead already established against Borussia Dortmund, Pep Guardiola's men relentlessly pushed for more goals at the Allianz Arena, leaving their visitors with no hope of a fightback in an eventual 5-1 triumph.

Guardiola: ‘It’s crazy to have won all eight games’

The result not only extended Bayern's perfect start to the 2015/16 Bundesliga campaign, it means they have won every game in all competitions this season. After the encounter, Guardiola expressed his delight with his team's displays, but also emphasised the need to stay grounded amid media questions about the title race.

"We won three points and obviously it's crazy to have won eight times from as many matches, but we're only eight games into a long season," said the 44-year-old. "Nobody's ever won the league in October. We'll only be German champions when we're actually German champions."

Echoes of treble-winning season

Nevertheless, Bayern are certainly well placed to defend their Bundesliga crown. The Bavarians are now seven points ahead of Dortmund in second, an advantage no league leader has ever had after eight rounds of matches. Furthermore, the only other side to win the first eight games of a new season (with a goal difference of plus 24) was Bayern themselves back in 2012/13 – the year they won the treble.

Still, other members of the Bayern camp swiftly quashed talk of silverware too. "I'm not going to talk about any topics like winning the league because so many things can still happen," said Thomas Müller, who scored Bayern's first two goals against BVB. "You always have to win your games first."

Bayern eyeing ‘magic four’

Sporting director Matthias Sammer struck a similar chord: "Before the season started we made it clear that the magic four [winning a fourth consecutive Bundesliga title] was something that greatly appealed to us. However, we need to remember we're only on Matchday 8 and we're running a marathon here."

That is undoubtedly true, but with records seemingly tumbling every week - for instance, Robert Lewandowski is now the first player in history to post a tally of nine goals over three successive Bundesliga matches - Bayern appear on course to reach the finish line at full sprint.
