Former England head coach Sir Clive Woodward has revealed that he spoke to England's current coach Stuart Lancaster about the dangers of social media to his team's World Cup campaign.
"It's the new enemy," said Woodward, speaking in this week's Radio Times.
"We didn't have to worry about it in 2003."
Woodward said he gave Lancaster the following advice regarding the matter: "Don't let the players be distracted. It could be the media, their family, sponsors, ticket requests, anything.
"One stupid tweet, one ill-judged video out on social media – if you allow one player to be distracted, it can affect the whole team, and it can all come tumbling down."
Woodward also claims that France would have won the 2011 RWC Final if the game was 'refereed properly'.
South African referee Craig Joubert was the man in charge of the 2011 final and Woodward believes his decisions in that clash helped the All Blacks to win the tournament for the first time since 1987.
"If I had been the coach of France in that World Cup, I would still be apoplectic to this day,"
"If that final had been refereed properly, France would have won."
