Following the announcement of next year's mountainous route, which is expected suit Froome over his team-mate, Wiggins initially said that he would focus on the Giro d'Italia rather than defend his title.
Froome himself told today's Times: "The team are saying they are going to back me with the Tour this year. That's directly from Dave [Brailsford]. He said: 'You're our man for the Tour. Focus on it."'
But team leader Brailsford has been more equivocal over the issue in recent days, opening up the possibility of Wiggins defending his title.
Wiggins, who followed up his Tour triumph with a gold medal in the London 2012 Olympic time trial and on Sunday was named as the BBC's Sports Personality of the Year, today said: "The last four years, all the focus has been on the Tour de France for me, trying to win that race. Fortunately I did it this year, then it's deciding what to do next."
