Messi's greatest weakness is penalties. Whoever chose to let him start instead of Aguero is an idiot.
Congrats to Claudio Bravo, he did a marvelous job during and after the match. Messi's growing legacy will not be cheapened or chipped at by the loss.
As I said in an earlier thread, glad he is retired, I don't believe he is, but I am glad either way. The Portuguese journalism were never as harsh with CR like the Argentinians are with Messi.
