Bradley Wiggins says he is likely to defend his Tour de France title after all next year despite previously nominating the Giro d'Italia as his main objective for 2013.
The 32-year-old Olympics time-trial gold medallist became the Tour's first British winner last July, with Team Sky colleague Chris Froome second.
At October's launch of next summer's 100th Tour Wiggins intimated May's Tour of Italy would be his priority, leaving the way clear for Froome to lead Sky's Tour assault.
But on Wednesday Wiggins told BBC Radio Five: "I don't know what the situation is in terms of leadership, as it stands I'm probably going to try and win a second Tour de France.
"I don't know, maybe we'll have two leaders, which is more than likely I guess. How that's going to work with the team I don't know, that's more (Team Sky general manager) Dave Brailsford's problem to worry about."
He added: "It's just how we service both mouths. Like I said that's more a problem for Dave to figure out, but my goal is to win the Tour next year.
"Whether that is realised or not I don't know really, we're still in this planning phase at the moment, deciding each race, what we're going to do next year, how we are going to go about training to do that.
"Whether I do the Tour of Italy before it, as I've said that is still undecided. All will be revealed in the coming months I guess."
If Froome is chosen to lead Team Sky, Wiggins insists he will support his team-mate.
"Oh yeah, I wouldn't be on the start line if not," he said.
"Whatever the team strategy is we all support that, otherwise you don't take the start line because there'll be somebody else that is willing to fulfil that job.
"It's a case of you do what's asked of you on the day, whatever that decision is."
