Nothing weird about that. He injured himself badly in the Tour, tried to make a comeback but clearly didn't have the level to compete.End of the season for Higuita. This was supposed to be his peak year and a lot was expected of him. It turned out to be a nightmare for him. Very strange that is done for the year. Maybe they know something that we don't know but weird nevertheless.
He's said in interviews he wants to be a Valverde-like rider. Link to article on the first page.Just a gut feeling but I think he will be a Valverde-like rider. Capable of good GC but not necessarily as strong in GTs as in classics and short stage races.
He did finish 14th in his GT debut in his first year in WT so he should be capable of good GC provided he will come back to his pre-lockdown level.
