There are some strange things. In the second week of the Tour, Giannetti confirmed to the Gazzetta that Pogacar would be going to the Vuelta. A few days later, it was leaked that Ayuso was changing agents and wanted to leave the UAE. Two days later, it was leaked that Ayuso could be going to the Vuelta for Pogacar.
At least Ayuso's situation seems connected. The news of his departure, and then two days later, he was included in the Vuelta a España when the UAE didn't want to include him in the 2 GT class because he was too young.
Giannetti said with great conviction in the Gazzetta that Pogacar was going to the Vuelta.
In that same interview, he was highly critical of Ayuso and again ruled him out for the Vuelta.
It could just be a coincidence. But the timing of everything is quite disturbing and gives reason to doubt that there's anything more to it.
