As a Brasil fan, i'm a bit embarrassed with that performance. Chile were the better team but I don't know if I can say they 'deserved' to go threw. They could have won that game in 90 minutes and again in extra time. But as time went on, they became bigger cowards, started playing defensive football and began to slow down the game. I think their historic shortcomings against A Seleção began to creep into their psyche. All in all it wasn't a performance I was proud of, but off to the final 8.
That said, changes need to be made by Scolari.
