you really felt the sting of Ramos' red card. After the match, Marcelo took the bullet by saying that he should have made a much more aggressive play towards Sergio Roberto even to the point of fouling him. Kroos had primary defensive responsibility there but he sank way too deep into the box and did not see Messi trailing the play. The rest is history.
How one does not account for Messi trailing the play is befuddling. Its not like he is the best player of his generation or anything. I give Real a lot of credit for the equalizer on a beautiful curl play from James getting fantastic service from Marcelo but they gambled big at the end and lost.
