Thomas is in form and must for now at least be seen as the main GC hope for Skineos. Dan Martin will be happy with his performance but there's a lot of tough days ahead and he's a woeful TTist. I see him hopefully in the bottom half of the top ten by Paris, anything better will be incredible.
Bardet is out of it as regards GC. Nibali too, probably because of his effort in the Giro. Quintana has a stage win in him but I don't see him on the podium. I can see a French rider on the podium but not on the top step.
