He points to Roglic 's WCC last year. I don't think he would just tag along and pick out two or three stages.
I think he would recover better than Roglic, he shouldn't forget that Roglic fell several times during the race including on stage 19 so if the Vuelta takes place I would like to see him there unless there is a conflict of dates with the rescheduled Ardennes classics.
Other option could be to ride a rescheduled Giro in October but I don't think it will take place.
