It was the best time to deliver a result for a man who finds himself without a Formula 1 drive for 2025, after being replaced by seven-time champion Lewis Hamilton.
There are vacant seats at teams elsewhere on the grid including the likes of Red Bull and Mercedes – who are in need of a dependable second driver.
He could also opt for a long-term project with the likes of Audi or Williams, but Sainz is likely in win now mode as he enters the prime of his career.
“Of course, his form is fascinating,” he said of Sainz.
“But you have to realise that Checo [Perez] delivered three good races this year. The fact that he fell back so much in Melbourne was due to the damaged underbody and tyre degradation.
“His only weakness is in qualifying. If he can improve there, there’s no need to think about it. The atmosphere in the team is very good also as far as he is concerned.”
For now, it seems that Red Bull are satisfied with Perez’s performances, with the Mexican having raised his levels this season.
If he can continue to back up Max Verstappen properly, he could drive himself into a fresh contract with the current fastest team on the grid.
