Netherlands 2 vs Slovakia 0
Slovakia is a pretty mediocre team from what I've seen, so NL should have no problems.
Brazil 3 vs Chile 1
Chile is a good team, but they make stupid mistakes as seen against Spain. First 20 minutes we'll see Chile attacking while Brazil stands back, then bad defending by Chile leads to Brazil's first goal. Medel will headbutt Kaka and get sent off. After that, all will go downhill. Chile will get a random goal, and be 2-1, but Brazil will seal the deal minutes later. Bielsa will have a heart attack and the match will be suspended, giving the victory to Brazil.
