He urged Williams to critically evaluate its internal capabilities to match competitor progress.
"And if we do not do the same, why? Why do we not have that capacity?"
Sainz said.
"So for me, it is important looking ahead to show that we can also have the capacity to make a turnaround like another midfield team has just done right before our eyes."
Comparing development baselines, Sainz highlighted how quickly competitive orders shift.
"So Aston went from less downforce, a worse chassis than us in Spa, to currently having the best downforce in the midfield," Sainz said.
"So it is up to us to find the solution to add downforce and find the evolution.
So I see it positively, in the sense that the team should look at that and say: yes, it is possible if you do things right."
However, upcoming upgrades scheduled for Baku in September face cautious scrutiny within the squad.
"I do not know what kind of upgrade Aston had, I can only dream of that, we can only dream of such an upgrade," Albon said.
"All credit to them.
