Brazil have fantastic attackers on an individual basis who don't seem to play well together as a group. Whether that's down to their coach or not, I dunno. Their defenders aren't really up to snuff though which is what will do them in at the next World Cup. They should try and get Marquinhos some time before 2014. If the top teams in the world want him right now, then I'd imagine he's good enough to get some minutes at the international level. It doesn't look like he played at the Olympics although he was on the team.
