Cologne - Unsurprisingly, the latest fascinating installment of Der Klassiker's long history stole the headlines on Matchday 27. Yet FC Bayern München's narrow victory over Borussia Dortmund wasn't the only talking point to have emerged from another topsy-turvy weekend of action in the German top flight.

bundesliga.com rounds up the five biggest talking points from an enthralling two days of football...

Dortmund fans hardly needed reminding of Robert Lewandowski's ability. The Pole scored his 44th goal at the Signal Iduna Park to settle a feisty Klassiker; though this time in Bayern colours. It was a first-half header which underlined the predatory qualities BVB have been missing during a season of toil. Indeed, despite Marco Reus and Co.'s best efforts, Jürgen Klopp's valiant troops failed to break down their old rivals' rearguard, slumping to a third successive home game without scoring.

Borussia Mönchengladbach were ruthless in dispatching TSG 1899 Hoffenheim 4-1, a display inspired by Patrick Herrmann. The winger netted his third brace of the season (more than the rest of his career combined) with a delicate touch and then an emphatic finish. Although closing in on UEFA Champions League qualification, six of the Foals' remaining seven fixtures come against top-half sides, meaning Herrmann will hope his purple patch continues a little while longer.

Andre Schürrle summed up his emotions after scoring in VfL Wolfsburg goal in three words. "I'm really relieved," he explained after netting in the Wolves' 3-1 home win over VfB Stuttgart, his first goal in 12 games. Dieter Hecking's second-placed troops brushed the league's basement boys aside in a powerful second-half showing, not only maintaining their unbeaten home record but also remaining firmly on course for the Champions League.

Slipping under the radar of the Klassiker headlines was Bayer 04 Leverkusen's rampant, Gonzalo Castro-inspired 4-0 success over free-falling Hamburger SV. The pint-sized midfield chief netted twice and picked up two assists (lifting his total to five in the past four games) as die Werkself romped to a fifth consecutive win without conceding. The irrepressible form of the 27-year-old has been a key factor as Roger Schmidt's side look well-placed to secure European football for another season.

Cruising at 2-0 against Hannover 96 in the 68th minute, Eintracht Frankfurt were well set to close the gap on seventh-placed Hoffenheim. Marcelo halved the deficit, however, before Didier Ya Konan netted the 17th goal Thomas Schaaf's side have conceded in the final quarter-hour this season. It is a familiar tale: the draw was the ninth time that the Eagles have dropped points after leading, a league-high. Indeed, were Schaaf's men as clinical as Bayern when ahead, they would be third.
