Add Carapaz to the Giro list, Roglič to the Tour list and Mas and Bardet to the Vuelta list, the (?) to Bernal that was very elusive and also to Pogacar because nothing is decided yet and take out the (?) from Quintana, the only doubt is the wildcard, if given he will be in France.So
Giro: Fuglsang, Bardet, Nibali, Pogacar, Haig (?)
Tour: Buchmann, Froome, Bernal, Valverde, Mas, Pinot, Domulin (?), Quintana (?), Lopez, S. Yates (?)
Vuelta: Valverde; Nibali
On lesser names we know that Latour and Gallopin will be the GC surrogate of Bardet for the Tour, Barguil will be for sure with Quintana in France and Calmejane has stated his desire to go to the Giro.
