The Australian has signed a three-year contract with McLaren, who are switching from Renault to Mercedes engines in 2021.

Ricciardo, who joins after two years at Renault, said: “Everything I have seen excites me about where McLaren is heading.

“I really believe in the personnel.”

He added: “They are doing what it takes to be a real contender in the championship.”

Ricciardo, who won seven races for Red Bull between 2014 and 2018 before deciding to leave for Renault, made the decision to join McLaren before the delayed start of last season, after just one season with the French car manufacturer.

He said he believed McLaren was his best option for the advent of a major technical rule change Formula 1 is introducing in 2022.

“We don’t have a crystal ball,” he said. “Leaving Red Bull or Renault, it is what I feel is right. Do I know how it will turn out? I don’t. But I certainly feel McLaren have done the right things to set themselves up in particular for these rule changes coming in 2022.”

Ricciardo joins Briton Lando Norris at the team that finished third in the constructors’ championship last season, winning a close fight with Racing Point and Renault behind dominant champions Mercedes and closest rivals Red Bull at the final race of the season.

He said he expected a similarly tough battle behind the top two teams in 2021.

“More teams than not finished on the podium last year,” Ricciardo said. “The battle to get to the front was getting more intense. For the rest of us, we are trying to close on Mercedes. I see it as most teams having a chance of a podium.”

Ricciardo had previous talks about joining McLaren when he left Red Bull, before ultimately deciding in favour of Renault.

He said he had been convinced McLaren were on the right track by the senior management changes at the team since, especially the hiring of Andreas Seidl as team principal and James Key as technical director.

McLaren ended 2018 with the second-slowest car on the grid, but have gone from sixth, to fourth to third in the championship in the last three years as these changes have come on stream.

Norris looking forward to the challenge

Norris said he had recovered from catching coronavirus over the winter, and that for him the disease “wasn’t too bad – it was a few days of having no taste and smell and just feeling very drained and tired for a couple of weeks”.

The 21-year-old, whose former team-mate Carlos Sainz has moved to Ferrari, said he saw the arrival of an experienced winner alongside him as “a positive – he can win and score podiums, do pretty much everything. I can learn more from a different driver. It is good to experience something different.”

Norris, who finished on the podium in the first race of last season on his way to ninth in the championship, did not set himself any specific targets for this year.

“I do my best and the people who know that more than anyone are the people I work with,” Norris said. “They know the effort and time spent and what I am good enough in and what I am not good enough in.

“Last year, I was very happy with how I did. There were things to improve but on the whole it was a much better season than year one (in 2019). I’m happy, but I have different things to work on and working alongside Daniel will help me become a better driver too.”
