Like i said in the race thread a few days ago, Ayuso is doing great, but we'll have to see how he finishes before jumping to conclusions. On stage 6 he was very strong, almost bridged to Evenepoel, but after closing the gap to 12 seconds, he faded hard and lost roughly 30 seconds in the final kilometers. On stage 8, he was dropped and lost considerable time together with Almeida, while Roglic, Rodriguez and Mas were all able to follow Evenepoel. I wouldn't be surprised if Ayuso has to let go the moment the climbs start getting longer. If stage 8 was an indicator, perhaps the flat part on Pico Jano saved him from dropping back further. His best performance relative to the others was on the steepest/shortest MTF on stage 9.
Maybe the climbs so far have been advantageous for him, but maybe the longer climbs coming up could see him fade a lot harder. If that is the case, that could be down to age, experience or simply physical ability. Maybe he turns out to be more of a Valverde type climber than a Bernal type climber. Or maybe his age permits him to be among the best on shorter climbs, but once the climbs get into double digits, he has to let go. He was also suffering in the TT, supposedly didn't feel well. Maybe he's reaching his limit and will soon start to lose loads of time. Hell, there is still a risk for Evenepoel to succumb to these same pitfalls. So i would not jump to conclusions yet. But if Ayuso doesn't lose significant time on the longer climbs, doesn't fade in the coming stages, then i guess Almeida's role within the team might change quickly. But for now i think it's still very well possible that Almeida finishes way ahead of Ayuso in GC come Madrid. Say Almeida is able to follow the best on Sierra Nevada, and Ayuso fades, we could be talking about minutes.
