Not sure what you mean. They won, but you consider it convincing? Colombia played a naive strategy, giving tons of space and gifting Brazil possession.
Also, they were stupidly engaging in a foul-a-thon which ate up time and disrupted any flow they could develop. The referee was awful, he wouldn't show a yellow for anything and players were falling down at the slightest contact all over the pitch. Typical S American garbage football, really.
If anyone believes that Brazil had any control of that game past 20 minutes, you're kidding. They finished the game substituting in defenders because they were backs to the wall. That's not a performance that should command the statement "how about those Brazilians now".
