Real Madrid are absolutely falling apart without Cristiano Ronaldo, though it's worth giving Borussia Dortmund plenty of credit for what they've done so far. They're tearing Los Merengues' defense to pieces and have two goals, both scored by Marco Reus. His first came after rounding Iker Casillas and his second was this effort at the end of a great counter, cleaning up after Robert Lewandowski hit the post.
The Madrid attack looks lost at the moment and Pepe has been extremely shaky in defense. This is truly anyone's tie.
