Brazil's forward Neymar (R) celebrates after scoring his team's second goal during the Russian Federation 2018 World Cup Group E football match between Brazil and Costa Rica at the Saint Petersburg Stadium in Saint Petersburg on June 22, 2018.
"I reacted to this episode quietly, but I was sad from such behavior on the part of Neymar for me", said Silva.
Neymar appeared to have been pulled down in the box by Giancarlo Gonzalez and Kuipers pointed to the spot, but the referee reviewed the incident and decided that the Costa Rican player's gentle tug was not enough to warrant the Paris Saint-Germain star's theatrical collapse.
Philippe Coutinho has urged patience from Brazil following the favourite's uneven start to the World Cup and the latest hysteria surrounding Neymar's fitness ahead of Friday's match against Costa Rica in St Petersburg.
Serbia, who have three points, play Switzerland, who drew with Brazil in their opener, later on Friday.
This was just his fourth appearance since breaking a bone in his foot against Marseille in February and only the second time he has completed the full 90 minutes.
But Costa Rica's packed-in camp held Brazil at bay into the break. My players made a huge effort, they defended well and whenever we had the chance to attack their goal they did. "But we only need to beat Croatia, which is possibly easier to say than do". They will face Serbia in their final match of the group next Wednesday. "The second half, it was attractive, perfect".
Celso Borges spurned arguably the best chance of the first period for Costa Rica when he ran on to Gamboa's cut back but shot wide from eight metres out.
"If I was the referee I wouldn't go back on my decision but I respect that because it's subject to interpretation", Tite added.
With his 56th worldwide goal, Neymar is now one ahead of Romario - which could be a useful omen for Brazil.
Prior to this match, the two sides had met each other twice in the World Cups with Brazil winning both the encounters.
Although left back Marcelo had an average game in defense, his constant runs down the flanks ultimately helped when his unsafe cross led to the opening goal.
Neymar is third on Brazil's all-time scorers' list, behind Pele (77) and Ronaldo (62).
