Ricciardo joined Red Bull in 2014 with the team having just secured
their fourth successive championship double with Sebastian Vettel.
The Aussie's arrival, though, coincided with the introduction of hybrid engines - and the rise of Mercedes.
While Ricciardo claimed three wins in his first year with Red Bull, he only managed to add another four since.
But the 29-year-old insists he has no regrets.
"No, I wouldn't say any regrets," Ricciardo, who has signed for Renault for 2019, told RACER. "Not at all actually.
"I guess as well I never really had many other options anyway, so
it's not like I could have signed with Mercedes two years ago and I
didn't want to or whatever.
"So no regrets. I'm happy.
"For sure I look at last year and 2015, there's been some frustrating

"So they're like, 'Ahh yeah, this did that,' and you're better off
