It's been a fantastic competition so far. I often find the group matches more interesting than the knockout matches, because teams tend to play more attacking football.
Going back a bit: Uss, Brazil didn't look great, but they didn't look bad either. They have the firepower to win the World Cup. Spain started slowly in 2010 and got through. So I'm not writing them off just yet.
Argentina looked way worse than Brazil - I thought they were very disappointing and lacked any killer punch. Messi is also one of my all time favourite players, not only for his incredible speed, control and ability to score goals, but also his attitude is a little more modest than some of the other great players. His goal in the game against Bosnia was absolutely perfect. But apart from that piece of genius, Argentina were almost outplayed by their less fancied opponents.
Chile v Australia was interesting because it looked like the Aussies were way out of their league at the start, but once they settled in, I thought they dominated the second half, and although we lost, I was encouraged by the way they played. Australia are one of the lowest ranked qualifiers, and will most likely come away with no points, but if they play like they did against Chile, I'll be satisfied.
Spain could be in trouble. It depends on how they can pick themselves up after the drubbing they received from Holland. No, they're not a 1-5 team, but their body language after that game was of complete dejection. It will be interesting to see how they react against Chile. The Dutch benefitted from van Persie and Robben (both not my favourite players, mainly for the simulation crap they usually pull) - they were both brilliant, and they are goal scorers. If you have 2 or more goal scorers in a team it helps your chances so much, and the opposition knows they have to closely mark them.
There have been some great matches! Costa Rica have blown open their group by upsetting Uruguay. Italy looked 100% better than I thought they would against England. Pirlo is a joy to watch, and Balotelli adds some potency up front. England looked reasonably good - Sterling and Sturridge looking the most dangerous for them. And Cote d'Ivoire stunned Japan with 2 quick goals!
This morning (my time

) Germany completely smashed Portugal, which surprised me (I haven't watched that one), and USA have pulled off a lucky win against Ghana. I say "lucky" because Ghana came at them like a tidal wave in the second half, and dominated, then scored and had all the momentum. The US then somehow converted the winning goal (great header too by Brooks). It was totally against the run of play. From a neutral perspective, it was a brilliant game to watch - really exciting, open and attacking game.
