Brazil forward Neymar has defended himself against accusations he over-acted after a challenge during the 2-0 World Cup last-16 win over Mexico, saying: "I just feel the pain."
Neymar, 26, reacted strongly to an incident in which Mexcio's Miguel Layun seemed to stand on his ankle.
Mexico coach Juan Carlos Osorio said the Paris St-Germain player's "acting" is "not a good example for football".
But Neymar said: "It's complicated. It's not something I can control."
He added: "I got stepped on unfairly. I think it was off the ball, outside the game. I don't think it should be done.
"But that's the thing, they talked too much before the game - and now they're going home."
Neymar scored one goal and played a key role in the other as his side set up a quarter-final against Belgium, who beat Japan 3-2 later on Monday.
However, he has faced accusations of diving at this year's World Cup.
Osorio said the incident with Layun halted Mexico's momentum, and that referee Gianluca Rocchi "favoured Brazil".
"It is a shame for football, we wasted a lot of time because of one player," said the Mexico boss after his side's loss.
"This is a game of men that is played with intensity and not with so much clowning.
"It is a shame for all the people watching, all the children watching. There shouldn't be acting. I think this had an impact on our pace and style.
"The game totally favoured Brazil. Too many interventions from the referee."
Neymar, who was given the lowest score by users of the BBC Player Rater, said the Brazilian players "have to learn to suffer".
"I don't care much for criticism, or praise, because this can influence your attitude," Neymar told TV Globo. "I think it's more an attempt to undermine me than anything else."
Brazil coach Tite defended his player and insisted Layun "stepped on him".
"I saw it on the screen," said Tite. "In the previous match, he was excellent and here he repeated a high-quality performance," he added.
