The next big thing for Brazil: Bernard. The highlight is more of a great scouting report than sick highlight, it does a good job of identifying him so you can keep track of him.
The video calls him an attacking midfielder, which isn't wrong since he usually plays on the left of the 3 in a 4-2-3-1, but I think he is better described as a forward, pedantic difference, but I think it's relevant.
He fits in any attacking role besides being the main striker, although he might develop that ability in a similar style to Messi if a team was built around him. He can play on either wing in a 4-3-3, or even centrally in a 4-2-3-1, but isn't really a classic playmaker who could move deeper and turn that into a 4-3-3 in the way that Oscar does for Brazil now. If he played in a 2 striker system he would fit very well playing just off another, more orthodox striker.
He's in Brazil's team for the Confederations cup and has come on twice as a sub. I think he will be much more prominent by the World Cup, and be a starter after that. His main competition for a spot, most likely on the right wing, will be Hulk right now and then Lucas Moura, who is faster, but not as versatile or as good of a decision maker.
The decision making is what really sets Bernard apart, he always seems to make the right play, never over elaborating but also never afraid to make the tough play either.
Currently he plays at Atletico Mineiro with Ronaldinho, a great example technically, but also a lesson in what can happen if you don't behave like a professional athlete, so hopefully he learns from him.
