"The Welsh hate them and I'm not going to mention the Irish. They create a consensus against them. The worst defeats are those against the English. Perhaps because they lack nobility in their victories."
The 2011 World Cup winner, known as Comical Ali, said on Twitter that the quotes were 'lost in translation'.
According to L'Equipe Williams had a dig at English fans, describing Twickenham as the worst stadium in the world to play at.
"It is the most hostile stadium there is. It's worse than Pretoria. The atmosphere is vindictive," he said.
"The supporters sing and applaud when we miss a penalty, and whistle us if we do something they disapprove of in terms of playing style. If the English, the only team nobody wants to see win, win this World Cup, it will be a dark day."
