MADRID - Bayern Munich faces a familiar problem as it travels to old European foe Real Madrid on Tuesday needing to make history to stay alive in the Champions League.

Cristiano Ronaldo's second-half double in Munich last week handed Madrid a 2-1 first-leg lead as the Portuguese became the first player to reach 100 European goals.

Ominously for Bayern, 11-time European champion Madrid has never failed to advance after winning the first leg away from home in the Champions League.
