Neymar, once seen as the next big phenomenon coming out of Brazil, has fallen by the wayside due to recurring injury problems. 

Neymar will undergo surgery for the injuries at a "yet-to-be-determined date," the CBF said, after a series of medical exams on the player in Sao Paulo.

Brazil midfielder Bruno Guimaraes admitted the World Cup favourites lacked some of their usual verve after they needed a late Casemiro strike to beat Switzerland and secure a place in the last 16.
