Gasly has now been dropped to Toro Rosso, and is likely to be overtaken by Sainz in sixth place in the standings as the Spaniard is just seven points behind, but Sainz has had no thoughts of what might have been had he remained with Red Bull.
"I'm doing well, I'm happy, I don't miss Red Bull. I was at the wrong time in the wrong place," Sainz told Movistar.
"On a personal level I knew that such a streak was inside me, that I could enjoy F1 like I never had before.
"In the midfield, being so consistent, it gives you things, it means that things are being done very well."
Sitting outside of one of F1's top three teams does have its drawbacks for Sainz, however.
Despite some fantastic drives putting him into 'best of the rest' contention, Sainz says he does not gain enough airtime, as he is not racing for victories.
"I get quite angry. Every time I scream at home because I do not get on the television," he said.
"You have missed important moments, such as the comeback in Austria. I went from 20th to eighth and nothing came out."
