(CNN) -- Champions League finalists Borussia Dortmund and Bayern Munich battled to a 1-1 draw Saturday in a feisty rehearsal for their May 25 showdown at Wembley.

Robert Lewandowski, who scored four goals in their Champions League semifinal first leg against Real Madrid, stepped up to take the kick and saw his effort brilliantly saved by Manuel Neuer.
Rafinha was then given his marching orders for elbowing Dortmund midfielder Jakub Blaszczykowski, leading to a heated exchange between Klopp and Bayern's sports director Matthias Sammer.
"No one came here thinking it would be a friendly," Klopp said after the game.
A man short, Bayern survived to the end despite a few scares.
They will play Augsburg next Saturday in their final home game where the Bundesliga shield will be presented.
Neuer, the stand-in captain for the day, was delighted they had survived the Dortmund test, thanks in good part to his penalty stop.
