Always good to speculate! My guess (in order of certainty):
Froome, Porte, Kiryienka, Boasson Hagen, Lopez, Thomas, Knees, Eisel, Siutsou
I don’t expect they’ll change too much from the Dauphine squad.
Pete Kennaugh had a good ride at the Dauphine, but I think they’ll opt for more experience in leading the peloton with Knees and Eisel.
Stannard can’t be far off the line-up, but Siutsou showed he’s in good nick at the Route du Sud and would offer more on the uphill bits, so I’m taking a punt on him for a place.
Then again, they might opt for more climbing support with the likes of Uran and Henao...
