With the only route to the Europa League through a victory in the DFB Pokal, Werkself overcame the never-say-die Bundesliga 2 side Mainz 4-2 in extra-time. The victory now books a date at the Olmypiastadion in the capital on 30 May against the winner of Wednesday's clash between Bremen and HSV.
After a tightly played match Greek international Angelos Charisteas broke the deadlock with eight minutes remaining as he pounced on a rebound and sent it in from a few metres out. With Werkself supporters anxious for Berlin, the celebration was delayed as two minutes before the whistle Montenegro international Milorad Peković's cross was headed-in by Aristide Bancé. Mainz was tiring quickly and only two minutes into extra-time Arturo Vidal gave Bayer 04 the goal they needed as he sent in a rebound from close range. Werkself added to the lead as Simon Rolfes headed-in Angelos Charisteas' corner to back of the net thirteen minutes into extra-time.
Michal Kadlec made it 4-1 as he completely split the opposition defenders, rounded the 'keeper to the right before scoring as supporters sung out "Berlin, Berlin, wir fahren nach Berlin!"
