On Saturday, Froome hinted he would be fine to see the GC stay as it all the way to Paris.
“That would be a dream scenario if that is the case, yep,” Froome told journalists outside of Sky bus Saturday.
Thomas started the Tour’s 14th stage to Mende leading Froome by 1:39, with Thomas Dumoulin (Sunweb) in third at 1:50 back.
So far, Froome has been downplaying any suggestion of fractures within the Team Sky bus.
“He’s ridden a faultless race so far and he’s prime position,” Froome said of Thomas.
The Thomas-Froome leadership question will continue as long as Thomas remains in front of Froome leading into the Pyrénées.
Froome also said he expects archrival Dumoulin to attack in the short but steep finale to Mende because the Dutchman can’t let the opportunity to attack slip by.
“My hunch is that he will probably have a go. He’s got to make up time,” Froome said. “He can’t rely on that final time trial to try to win this Tour. He’s got a minute-forty, minute-fifty to try to make up, he can’t leave it too long.
“There are only two uphill finishes left to go — one in the Pyrénées and one today — I can imagine he will have a go.”
