I'm not convinced he can get close to him either, (Pidcock or Hayter in a classic/1 dayer maybe but not in a 3 week tour at the moment) but I'm not sure who else they have at the moment who could either, and at least Thomas seems to be on good form...
I thought Ineos were largely against disc brakes?
I’m not convinced a 36 year old Geraint Thomas can get close to Pogacar on his day.
Edit: apparently they’re fully behind disc brakes since last September https://www.cyclingnews.com/news/ineos-grenadiers-finally-switches-to-disc-brakes/
