Daniel Ricciardo believes new Toro Rosso driver Carlos Sainz Jr is "very well prepared" for the step up to F1 after winning the Formula Renault 3.5 title.

Sainz Jr will drive alongside Max Verstappen in 2015, effectively replacing Daniil Kvyat who has been promoted to Ricciardo's team-mate at Red Bull. Having himself come through from FR3.5 in to Toro Rosso, Ricciardo said he has no doubts over Sainz Jr's talents and expects him to adapt well to the pressures of Formula One.

"I think he's very well prepared to move up," Ricciardo said. "He's impressed with the driving side of things and has the talent, so he won't run into any difficulties behind the wheel. The real challenge will be to get his head around the rest of Formula One: dealing with the demands out of the car - but he's a level-headed guy so I think he'll get up to speed with that stuff fairly quickly."

And Ricciardo believes FR3.5 has shown itself to be a strong feeder series for F1 compared to GP2. Asked if it was the right launch pad for Sainz Jr, Ricciardo replied: "Definitely.

"It was for me and since then the cars have got considerably faster so, if anything, it's even better now than it was a few years ago. In terms of getting up to the physical speed of Formula One, I think it's a lot closer now. I don't expect there will be too much to faze Carlos. Obviously Formula One is quicker and there's a lot more going on."

With Toro Rosso fielding two young rookies in 2015, Ricciardo said the team provides the right type of environment for young drivers to succeed.

"It's definitely a good place to come into F1 because there are a lot of experienced people in that team and I think that's what you need. You need guidance from people who've been there and done that. In a way, what you really need is for them to talk it down. Getting an F1 drive is pretty exciting! You want people who can downplay that, keep you on the level and feed you into it slowly. Obviously they did a lot of good things for my career and I'm sure they'll guide Carlos in the same way. I think he'll find a nice home there."
