I wouldn't be so quick to write-off Brasil. Without that crucial error in the first half, there might not have been a penalty shoot-out to witness. Also, while Columbia may look impressive, consider the games they played. Their group wasn't exactly the group of death. And beating a Suarez-less Uruguay team was done by Costa Rica (not to say it is an easy task, but there is a HUGE difference between Uruguay with their star man and without him).
Although Columbia will be brimming with confidence now, they are far from clinching the trophy, let alone knocking out the host nation.
