Ricardo Quaresma makes it 2-0 Porto after another Bayern Munich error

What on earth is happening to Bayern Munich? First, Xabi Alonso gave the ball away, leading to a penalty. Then, just seven minutes later, Dante committed the same sin, touching the ball directly to an FC Porto player. This time it was Ricardo Quaresma who got the gift from Bayern's defense, and he finished to score his second of the game. Incredibly, FC Porto lead Bayern Munich 2-0.
