It needs someone with the “second is first loser” mentality to give it a go, and unless Movistar can arrange for Quintana / Valverde to work together in a death or glory mission I can’t see anyone else being able to out-Sky the team.
My thoughts exactly. Movistar need to be prepared to sacrifice one of them. Assuming Quintana as leader, Valverde has to go for a full bore attack to stand a chance of breaking Froome. Sky will be forced to bring him back and that might give Quintana a chance to get away. Repeated little digs don’t seem to do anything as the Sky train just TT’s back on to the wheel.
A Bertie Inn steak dinner might for Valverde liven things up nicely but that’s a comment for the other thread…
