He is a hyped player in brazil by their coach, and he is not just hyped for hyping sake, but because they all recognize that his creativity and experience is a key factor for the team. In Brazils first goal against Serbia, Neymar's creativity got the ball close to Vinicius to push it the way of Richarlison to score. Great news that his injury has not completely taking him out of the world cup completely.
