Cologne - From north to south, there were once again plenty of talking points in a dramatic weekend of Bundesliga action on Matchday 23.

bundesliga.com summarises the five biggest stories to emerge from another unforgettable weekend in the league of the world champions...

The 146th Revierderby between Borussia Dortmund and FC Schalke 04 was a truly memorable occasion and arguably the Yellow-Blacks' best performance of the season. BVB swarmed all over their neighbours at the Signal Iduna park, restricting Schalke to just three shots all game while firing off 31 of their own, with all three goals coming in a barmy eight-minute spell in the second half. It's now four straight league wins for Dortmund, who are coming good when it matters most.

Dortmund's derby heroes were not the only ones with reason to celebrate on Matchday 23, as FC Bayern marked the 115th anniversary of the club's founding prior to kick-off at home to 1. FC Köln on Friday by unfurling an enormous banner with a picture of a tree (l.), accompanied by the words: "The seed we planted has grown wonderfully." Köln failed to spoil the party as Pep Guardiola's charges emerged 4-1 victors, and have now scored 20 goals in their last four league outings.

Most players may publicly state that winning the Torjägerkanone as Bundesliga top scorer is of secondary importance, but that has not stopped Arjen Robben and Alex Meier grabbing the ball to take their teams' penalties in recent weeks. The latter hit a brace on Saturday to take his tally for the season to 16, just one behind the Bayern No10. And don't forget, Bas Dost and Robert Lewandowski have also been among the goals and won't be giving up just yet...

Borussia Mönchengladbach bucked the trend on two fronts in their 2-0 home win over SC Paderborn 07 on Sunday afternoon. It was the first time this season they'd managed to pick up all three points immediately after a European game and also the first time this calendar year they'd scored more than one goal in a single league game. Lucien Favre's side now have a four-point cushion on fourth-placed Bayer 04 Leverkusen, while Paderborn drop into the bottom three for the first time.

Dost continues to blaze a trail in the Bundesliga in 2015 after netting his 10th and 11th goals of the year in VfL Wolfsburg's spectacular 5-3 win over SV Werder Bremen. With eight goals in his last three games, he has matched a feat last achieved by Robert Vittek in 2006, with everything he touches turning to goals. Indeed, nine of his last ten shots have found the back of the net, while he has scored more than one in four of the Wolves' six Rückrunde matches. Talk about efficient.
