I support Cruzeiro, so I've watched virtually every game he played in professional football. He really looks like the kind of kid who would do well in the PL, and I expect him to become a world-class midfielder and an important figure for the national side.
Last year he started on the bench and became a first team player during the league. He was outstanding, turning out to be one of our best players in several matches. He simply destroyed Seedorf on the most important game of the season. And, well, we won it, so it's not that easy to start games for the team. He also did a good job with the U21's (I guess) national team.
About his style of play, he's kind of a mid-term midfielder. He's neither a bulldog-DM (like de Jong) nor a regular playmaker like Modric, but he can give a lot of cover in defense and has very good passing hability (he really really really likes long passes). He reminds me a little of Carrick in the way he positions himself in defense, but he does tackles more often. He also has very good workrate and long-range shoots. I think his best place should be deeper in midfield, and that's how he usually plays for the club.
The only relevant down about him is that he is not that confortable on the ball when under pressure, which leads to him giving it away or taking a wrong decision that spoils the attack. But he probably will get better at this with experience.
I hope he could sign for United one day, but I doubt he will leave now, since we are in the middle of the league (with good chances of winning it). Maybe a January signing. He would have to leave for Rojo-like money, though, unless there's a buyout clause I don't know about.
