Neymar, 26, reacted strongly to an incident in which Mexcio's Miguel Layun seemed to stand on his ankle.
The 20-second-clip features children running on a field, each dodging their own football.
Jesus, meanwhile, has failed to score in any of Brazil's games but the assistant said the 21-year old was still an integral part of a team that is getting better with each game and now moves into a quarter-final game with either Belgium or Japan.
"Neymar is probably the best player I've ever played with or against".
"We had control of the match, but to me it is just shameful that so much time could be lost over one player", the Mexico coach said, according to ESPN.
But before setting up the second goal it looked like Neymar's game - or even his World Cup - could be over with 20 minutes to go.

"Neymar does not need [to do] it". The goal somewhat changed the momentum of the game as Brazil started playing attacking football and Mexico opted for counterattacks.
There is also "WBS", which is presumably the initials of Chelsea player Willian Borges de Silva, and CasAo is likely Real Madrid player Casemiro, as Neymar tagged both players in the picture.

"With Lionel Messi gone and Cristiano Ronaldo gone, you could argue that Neymar is the biggest star left in this tournament". But I mean the pain threshold of Neymar is just incredibly low, I must admit.

Thiago Silva is preparing to face a "very strong" Belgium in the quarter-finals and knows Brazil can not become complacent amid their status as World Cup favourites.
Martinez certainly had the last laugh, as his decision to bring on Chadli and Fellaini when chasing two (or three) goals was widely mocked on Twitter.
