Frankfurt captain Pirmin Schwegler hailed Borussia Dortmund as "the best team in Germany right now" after his team fought back to secure a thrilling 3-3 draw against the back-to-back Bundesliga champions.
Schwegler was left to reflect on a "magical evening" - but Borussia's star names were less happy after watching a three-point haul slip from their grasp.
Mats Hummels stormed past waiting reporters, and the local Ruhr Nachrichten newspaper reported that the Germany international defender later vented his frustration at the goals his team had let in.
"It is fatal. We concede too many goals," the Dortmund captain, Sebastian Kehl, said after the match. "In defence, we are not as tight as last season."
Coach Jurgen Klopp, who was sent to the stands after an injury-time confrontation with the fourth official, said: "We have conceded the third most goals. This is a damning statistic."
Bayern Munich, on the other hand, have claimed five wins out of five this season, leaving them seven points in front of Dortmund.
About a year ago, on matchday six of the 2011-2012 season, the Bavarians opened up an eight-point lead - but ended up losing the title to Dortmund by the same margin.
And that has led to a wariness in their players' approach to their current fine start, with Arjen Robben saying: "Thirty-four matches have to be played, and we have played only five now. We must stay calm and keep both feet on the ground."
Chief executive Karl-Heinz Rummenigge took a similar line, saying: "We are having a good run. We play good football. But there is no reason to become euphoric."
But in an interview with kicker, in-form Mario Mandzukic - who has scored five goals in the five wins - said: "If we continue like this, we don't have to look at the other teams. I want titles. More than one. That's how you write history."
Dortmund are being equally cautious in what they say, with director of football Michael Zorc stressing: "Top of the table is not where we are looking at - we did not do that last year, and will not do it this year."
