Brazil's Thiago Silva has revealed that Neymar gave him a foul-mouthed earful for returning the ball to Costa Rica after a stoppage in play during the Seleçao's 2-0 World Cup victory over Los Ticos on Friday.
Neymar and Philippe Coutinho both scored second-half stoppage-time goals to give the Selecao their first win of the tournament in Russian Federation, but before that, Silva says his Paris Saint-Germain teammate had harsh words for him after he kicked the ball back to Costa Rica in the 83rd minute.
It was only the second time that Gabriel Jesus and Firmino have played together for Brazil - the other time was for the final few minutes of a match against Chile in South American qualifying - and they combined to contribute to Coutinho's go-ahead goal in the first minute of stoppage time.
His first touch took the ball away from the defender and Coutinho raced in to poke it through the legs of Keylor Navas from six metres out and claim his second goal of the tournament.
At first, referee Bjorn Kuipers gave the spot-kick but the incident was looked at again by VAR and, though Gonzalez did grab at Neymar's jersey as he slipped, the contact appeared minimal prior to the world's most expensive footballer hitting the deck.
The result takes Brazil to the top of Group E with four points, while Costa Rica have none and therefore exit the competition.
It came at the flawless time with Brazil set to face a tough Serbia squad and the confidence they gained with this win could help them get three more points against the European squad. Clearly overjoyed with the performance of the team, Brazilian football coach Tite ended up skipping a step and falling on the ground while running towards the players.

Diego Maradona has requested a meeting with the Argentina team ahead of their final Group D game against Nigeria on Tuesday. Former Barca midfielder Emmanuel Petit, who won the World Cup with France, wants to see a better mentality from Messi.
Both Firmino and Costa had come on as substitutes in the second half.
A defeat would have put the Super Eagles out of contention, but Ahmed Musa struck twice to become the first Nigerian player to score at two World Cups.
Meanwhile, Costa Rica have knocked out of the tournament after failing to notch any point from two games.
"Messi is very good, but it is clear that he is very good because he is surrounded by extraordinary players (at Barcelona)", said Simeone, who now manages Atletico Madrid.
It was a though game for Brazil after opening draw against Switzerland.
Brazil's 2-0 victory over Costa Rica was anything but simple on Friday. They will face Serbia in their final match of the group next Wednesday. If Argentina win they still have a chance of finishing second behind the already-qualified Croatia and reaching the knockout stage.
Coutinho has been directly involved in four goals in his last four games for Brazil (three goals, one assist), as many as in his previous 14 combined for the national side.
