"I think a lot of people expected me to take the soft option and stay because they see me as a soft guy," Ricciardo told Fairfax Media in an exclusive interview. "I'm maybe perceived as someone who is a friendly guy who wouldn't push back and make a big decision. It's good for everyone to see that I have the balls to make a call like this." For most of 2018, much of the speculation over Ricciardo's future focused on Mercedes and Ferrari if he was to leave the only F1 family he's ever known. His five seasons at Red Bull Racing follow a two-year apprenticeship at its sister team, Toro Rosso. Mercedes has been the sport's dominant team since F1 switched to V6 turbo hybrid engines in 2014, while Ferrari, with Sebastian Vettel leading its charge, seemed the squad most likely to knock Mercedes from its perch. But doors that could have flapped open never quite came ajar. As Ferrari dithered over whether to retain Vettel's 38-year-old teammate Kimi Raikkonen or promote promising young Monegasque driver Charles Leclerc, Mercedes elected to re-sign Valtteri Bottas to play support act to world champion Lewis Hamilton for a third season in 2019. With a bottleneck at the top two teams, most expected Ricciardo to stay with Red Bull, where he's demonstrated an ability to win multiple races in machinery that, in his tenure, has never been capable of a championship push. But a surprise player came onto the scene in the immediate aftermath of Ricciardo's second win this season, around the streets of Monaco.

"Renault first expressed some interest around then, with Cyril [Abiteboul, Renault F1 managing director] contacting Glenn [Beavis, Ricciardo's manager]," he says. "There were several options. I spoke to Renault, I had a couple of meetings with McLaren, and I got to speak with [Red Bull company founder] Dietrich [Mateschitz] in Barcelona and again in Austria. "Initially, I had it in my mind that I'd be staying [at Red Bull]. But the more I thought about starting something different and taking on a new challenge, I got excited. I met with Renault and got a sense for their long-term plan. Obviously I want to win tomorrow, but the strength of Ferrari and Mercedes at the moment means it's very hard for anyone to take them on in the short-term." A load off: All instincts told Daniel Ricciardo he had made the right choice. Credit:PA Ricciardo says Renault didn't promise him the earth – in fact, the French team did quite the opposite.

"The thing that struck me about Renault was that they were prepared to be honest," he says. "Straight away, they said 'we're not going to be quicker than Red Bull next year', but what they told me about their plans for 2020 and for when the next rule changes come in for '21 … they had some good structure in place, they're recruiting a lot of good key people, and they're preparing to win. They have a winning mentality and a realistic way of going about it, which I liked." As Renault's approach became more serious, Ricciardo still had a two-year deal from Red Bull on the table, but something about the thought of standing pat didn’t feel quite right. "There's been times this year that I've felt exhausted, maybe a bit jaded, and for the first time in my career, not completely enjoying F1," Ricciardo admits. "There's been times when I've thought 'this is why [2016 world champion Nico] Rosberg retired', and he had it a lot more intense than me. Or why Casey Stoner retired from MotoGP very young. I can see how you could feel burnt out or a bit over it.

"I pushed for a one-year deal, which Red Bull agreed to, but still in the back of my mind, I wasn't sure. What if I was in the same position, had the same feeling a year from now? Would there still be other options available? I didn't want to snooker myself." Loading Renault set a deadline for Ricciardo to accept its two-year deal over the Hungarian Grand Prix weekend in late July, but he needed more time to ponder his options. "Renault wanted an answer in Budapest, and the Red Bull offer was still there," he says. "There was too much going on, so I managed to buy a few more days. But I had to make a call."

Three days after that race weekend, Ricciardo was in London, bound for LA, and with a decision to make. He'd been on the phone to his manager right up until his flight boarded. "For the first time in I can't remember how long, I had 10 hours to myself, didn't need to be at a race weekend, didn’t need to be at an event, and I was on my own time," Ricciardo says. "There was something about being alone on that flight that gave me the clarity I needed. The one thing I kept coming back to was being energised again, wanting a new challenge, and that the chance to change excited me. So as we got phone signal as I was coming into LA, I called Glenn and told him it was Renault." Ricciardo met his three friends in LA, and as the quartet headed to Las Vegas for the weekend, spent most of the four-hour drive on the phone. "The others all went out when we got to Vegas, but I stayed in the hotel because of how exhausted I was," he says.

"The next morning, I called [Red Bull motorsport adviser] Helmut [Marko] and then [team principal] Christian [Horner]. Helmut said he wasn't too surprised, that he expected it in a way. He said he had a feeling that I wanted to move on. Christian, at first anyway, thought I was taking the piss. "After I'd made those calls, I felt like a big weight had come off my shoulders straight away. They weren't easy calls to make. But my instinct was telling me it was right. My gut feel was telling me it was right. I was waiting to have that feeling the whole way through the process as it went for months, and I got it for the first time on that flight to LA. When I finished that last phone call and it was done, I knew. I turned my phone off and left it in the hotel safe for three days …" Ricciardo says the decision to leave is "one of the toughest" he's made in life, not just his racing career. "It's been a 10-year journey with Red Bull. I was in their junior program in 2008, so amazing memories and things I'll always be grateful for, and things I'll never forget," he says. "I'm sad to move on, absolutely, but excited by the challenge at Renault. Personally I felt it was good for me to have a fresh start somewhere else, I think it will be healthy.
