Neymar had an incident-filled outing, seeing a penalty overturned by a VAR review before scoring the second of his side’s stoppage-time goals after Philippe Coutinho had broken the deadlock.
Following the game, the superstar forward was seen in tears with his head in his hands as his team-mates celebrated a crucial Group E victory in St Petersburg.
Before Coutinho's breakthrough, the 26-year-old had lambasted Silva for returning the ball to Costa Rica in an act of fair play, much to the disappointment of his Paris Saint-Germain team-mate.
"I was saddened by his behaviour," Silva said.
"By the time I returned the ball, he insulted me. But I think I was right, because they were trying to save time.
"I returned the ball because it was not this ball that was going to win us the game.
"I am serene about this and I was sad about his behaviour towards me."
