FIFA president Sepp Blatter has criticized the actions of Luis Suarez, saying that the Uruguay forward's bite on Italy's Giorgio Chiellini goes against the values he is trying to instil in world football.
The governing body handed Suarez a nine-match international ban and a four-month suspension from all football-related activity after the incident in last Tuesday's Group D clash.
Blatter was unwilling to comment on the punishment, but said Suarez's actions were unacceptable when it came to the general ethics of fair play in the game.

"I am fighting for fair play on the field of play and fair play off the field of play," the 78-year-old told journalists. "But especially on the field of play and this is not fair what he has done. It's definitely not fair.
"Now to discuss the decision that has been taken by a panel of seven judges. It's not up to me to make a comment on that. Obviously they have taken into consideration the other incidents of this player who has already been banned in football or suspended in football for the same activity.
"I cannot say whether it is too much or too little. This is an independent decision from FIFA."
Blatter, who recently announced that he would like to run for another term as FIFA head, said that otherwise he has been delighted with how the tournament is progressing with most teams playing attacking football.
A total of 136 goals have been scored at an average of 2.83 per game.
"I'm not the only one who is impressed by that [the quality of games]" he said. "What has changed from the former World Cups is that in the first matches in the first round, everybody wanted to win, not to not lose. The football was exceptional right up to the last matches, the third matches.
"In the third matches there are tactics to maintain a result but still it was very exciting and results [were] only decided in the last minutes of matches."
