Daniel Ricciardo believes Sebastian Vettel was keen to move to Ferrari because winning his fifth title with a different team will be more satisfying that doing it at Red Bull.

Vettel won four consecutive championships from 2010-2013 with Red Bull before enduring a tough season this year as Ricciardo comprehensively outperformed his team-mate. However, Ricciardo doesn't believe Vettel's decision to move to Ferrari had anything to do with losing to his team-mate, but says the goal of winning his next title with another team would be more appealing.

"I think it's probably just made the situation more clear for Seb in terms of ... obviously he didn't have the year he would have liked to have had and it's probably just put everything into perspective," Ricciardo said during an interview published on Crash.net. "He's won four titles at Red Bull. To win a fifth at Red Bull is that going to be as satisfying as maybe winning one with another team?

"And I know he's pretty passionate about Ferrari and even their road cars. I know he's a fan of the company, of the product, so I think it probably wasn't a hard decision in the end, you know from his point of view."

And Ricciardo attributes his own performances in 2014 to having less pressure on his shoulders than Vettel as Red Bull tried to defend the drivers' and constructors' titles.

"Definitely the way I looked at it was if anything there was more pressure on Seb than on me because if the car was expected to win, if we were expected to go to Melbourne with the quickest car then no-one was expecting me to win. It was "Okay Seb should be the winner and maybe Daniel might get a podium or might get a top five". So with that it was easy for me to just come in, do my thing and I think that was the best approach. So yes it all worked out really well."
