The 80,000 spectators packed inside Germany's largest stadium will stand up in unison to pay tribute to a man who has led the club through one of their most successful spells ever. Step forward Jürgen Klopp.
bundesliga.com has all the information you need to look forward to an emotional occasion when Borussia Dortmund host SV Werder Bremen this Saturday (kick-off 15:30 CEST / 13:30 GMT).
Aside from this being – the club he led to two Bundesliga titles, a DFB Cup win and the final of the UEFA Champions League – there is still the not-so-small matter of European qualification to be determined. If Dortmund finish seventh they would be guaranteed a place in the UEFA Europa League next season, irrespective of their result in the DFB Cup final against VfL Wolfsburg, while Bremen would have to rely on BVB lifting the cup should they win on Saturday and clinch seventh for themselves.

bids the Bundesliga farewell this weekend ahead of his retirement this summer. He will be remembered as a strong midfielder – both physically and mentally – who defined an era at the Westphalian club, always leading by example right up to the last, which will be next weekend's DFB Cup final.
has delivered his fair share of free-kick goals this season and one could make the difference on Saturday. His support in midfield will be crucial to exerting pressure on the Dortmund back line and, even if they cannot penetrate, getting a set-piece in close proximity to the goal is just as good when Junuzovic is around.
Jürgen Klopp, head coach: "[Qualifying for the Europa League] would mean everything. Absolutely everything. We've been playing in the Champions League for four years and now we can see what's changed in the Europa League."
Klopp: "Zu allem kommt, dass am Samstag ein großer Borusse zum letzten Mal für Borussia Dortmund spielt.“ #dankekehli— Borussia Dortmund (@BVB) May 21, 2015
Viktor Skripnik, head coach: "I hope that my team don't just want to take a look around the stadium, but that they will give everything to win this game. It's fantastic that we're at the focus of the attention in a 'final for Europe'. I'm delighted there's still something to play for."
Dortmund's run of five games unbeaten was brought to an end by Wolfsburg last weekend, denting their European qualification hopes slightly, but not significantly. Bremen could have moved ahead of them had they not been beaten at home by Borussia Mönchengladbach, a result which ended a four-game unbeaten streak.
This will be the 94th meeting between two of German football's biggest clubs and the head-to-head record is rather balanced with 40 wins for Dortmund and 37 for Bremen. Bremen got the better of BVB in the reverse fixture this season, but they have not won at the Signal Iduna Park since April 2007.
Dortmund: Weidenfeller - Durm, Sokratis, Hummels, Schmelzer - Kehl, Gündogan - Mkhitaryan, Kagawa, Reus - Aubameyang
Bremen: Casteels - Gebre Selassie, Prödl, Vestergaard, Sternberg - Bargfrede - Öztunali, Bartels - Junuzovic - di Santo, Selke
