Well, this match hasn't really started according to plan. Brazil are finding it impossible to retain possession, and South Korea are converting their dominance into genuine chances. The score remains at 0-0, but you could argue that the favourites should already have found themselves down by a couple of goals -- Gabriel's been taken completely out of the picture twice and Thiago Silva and Sandro have both been forced into goalline clearances.
The most dangerous moment of the game, as far as Brazil are concerned, came in the 15th minute, when Gabriel decided to make a thoroughly ill-conceived challenge for the ball, which popped up for Ji Dong-Wong. Juan got the ball partially away from the Sunderland striker by kicking him in the head (which isn't a foul no, apparently), and Thiago Silva managed to scramble the ball away. That was an incredibly close call, and I can't imagine that Brazil are very happy right now. They have to get the ball and hold it, or they're going to lose this match.
