There were already problems with Ayuso in the last TDF.
Almeida seems more resigned to being a domestique in GT, but in reality, he barely had to work as a domestique last year because Pogacar was far superior, and Yates was the decisive domestique the following stage after Lioran. The day that Pogacar had more doubts and needed the punctual sacrifice of a teammate.
If Yates is fatigued this year and Pogacar has a problem and needs Almeida to do what Yates did, sacrificing time, we'll see if Almeida does it or if problems arise like those with Ayuso.
For Pogacar, having Ayuso or no one is the same. For him is better to have someone of a lower level than Ayuso, since he won't act as a domestique.
Last year, Almeida was fortunate enough not to have to be decisive. If he has to be this year, that's when he'll have to prove he'll sacrifice his chances, and in good shape, not fatigued from competing all the one-week races.
