Brazil captain Thiago Silva has branded Colombia defender Juan Zuniga a "coward".
Napoli defender Zuniga's challenge on Neymar left the Barcelona star with a serious back injury and ruled him out for the remainder of the World Cup.
"It was a coward's tackle," said PSG defender Thiago Silva.
"Some people say it was normal, but I don't think it was.
"That kind of challenge isn't done. You can't get the ball from someone by putting your knee into a player's back, it's not normal."
