McLaren has confirmed Fernando Alonso will continue with the team into the 2018 Formula 1 season, saying he is happy and it is "where his heart told him to stay".
But now that McLaren and Renault-which powered Alonso's 2004 and 2005 championship wins-have paired up, the Spaniard has faith in the team.
McLaren executive director Zak Brown said: "Fernando has been a fantastic asset to the whole organisation for the past three years, is an incredible individual and is one of the most accomplished and talented racing drivers of the modern era".
"I really feel at home here", Alonso says.
Things are finally looking up for Alonso in F1 after years of struggle.
"It's fantastic to be able to continue my relationship with everybody at McLaren", Alonso said in a statement.
"Although the last few years have not been easy, we have never forgotten how to win, and I believe we can achieve that again soon".
"Just as important, McLaren has the technical resource and financial strength to be able to very quickly win races and world championships in F1", said Alonso.
McLaren have gone some way toward answering those doubts by ending a troubled partnership with Honda and switching to Renault engines in 2018.
Honda's unreliable, underpowered engine has been a sticking point for Alonso since it debuted in 2015.
Mario Andretti, who won the 1978 F1 world title, has always been a fan of Alonso, but his admiration has grown after watching how the Spaniard took on the task of racing at the Indianapolis 500 in May.
"We left all doors open, I talked to everybody who wanted to talk, with all the different projects I had on the table, but the most convincing one was McLaren's". He has already won the Monaco Grand Prix twice, one of them with McLaren.
However, this means that if you wanted to see him make another run at the Indianapolis 500, you'll have to wait. "Let's see what we can do next year, but definitely happy again to have a Renault engine on my auto". "In their own mind I'm sure McLaren made the right decision so I hope that they did", he added. Thankfully, since McLaren will run Renault power units next year, they might actually have a competitive auto. And so does Fernando. Fernando fully understands and buys in to the direction we are taking.
"There are racing drivers and then then there are racers".
