Philipp Lahm calls for "courage and passion"

Bayern Munich captain Philipp Lahm believes that the team that shows the most "courage and passion" will advance from their Champions League semi-final against Real Madrid.

The German outfit, who are the holders of the competition, overcame Los Blancos at this stage of the competition in 2011.

"These are two giants facing one another, of an international level and the winner could be the one who shows the most courage," Lahm told reporters at a press conference.

"Also, quality and play will factor, but most of all, courage. Games like these are decided by courage and passion."

Bayern are aiming to become the first team to successfully defend the Champions League since AC Milan in 1990.
