Wiggins was the first Briton to win the world's most famous cycle
race in 2012 but team leader Froome said a place even as a super
domestique rider was by no means certain just over a month before
the endurance classic gets underway in Leeds on July 5.
"Talking about a Plan B, that's a decision the team needs to come
to, and Bradley has been talking about playing a support role, not
being our Plan B as such," fellow Briton Froome told the Daily
"Richie is looking pretty good at the moment and has the potential
to be riding for a place on the podium.
"As far as Bradley is concerned, the final nine riders selected to
start the race in Yorkshire is a hot topic.
"That's going to come down to what is best for the team, who is best
for each role and the team dynamics."
Wiggins announced his intention of racing in the Tour de France
after an impressive victory in the Tour of California last month.
Already tense relations between the two riders were likely to have
been further strained after Froome's recently released book revealed
they had fallen out in 2012.
"I would have been criticized a lot for not covering that topic in
my autobiography," Froome told the paper.

"Until now people have only seen Bradley's version of events, so it
was important for me to put out what I felt happened. But these
issues have been put to bed and are in the past now."
The 29-year-old Porte played a key support role in Froome's victory
last year, acting as his main climbing deputy in the major mountain
stages on his way to a 19th place finish.
