I think it would be good for Del Toro to do the Tour alongside Pogacar, if he goes with the right attitude, not like Ayuso. That's how some riders started, like Lemmond alongside Hinault.
I wouldn't rush him to go to the Giro. Besides, Vingegaard will go to the Giro, and we have to be realistic; if he hasn't been able to beat Simon Yates, he won't be able to do it with Vingegaard in a few months.
The Tour is a race they have to know; it's very different from any other GT, and doing it as a domestique without any pressure other than helping is a good way to go.
He could even lead other one-week races, and if he goes to the Tour as a domestique, he won't be as tired as if he went to the Vuelta as a leader and could extend his season in autul. Almeida is completely coocked after the Vuelta.
