Felipe Massa is satisfied with the achievements he managed during his 15-year career in Formula 1, claiming he "fulfilled all my dreams" in the sport.

The Brazilian announced his retirement from the sport at the end of 2017 after agreeing to stay on for one last season back in January at Williams, allowing Valtteri Bottas to make the move to Mercedes.

Another solid year would follow, leading the Grove team's challenge alongside rookie Lance Stroll, but a lack of development would set the team back mid-season meaning they finished fifth in the Constructors' Championship.

Reflecting on his career, which began at Sauber in 2002 and was most notable for his eight-year stint at Ferrari, partnering the likes of Michael Schumacher and Fernando Alonso, Massa insists he has no regrets.

"The only thing that was missing for me was a world title and I believe that I was the Brazilian driver who came closest to do that, from those who were not champions," he said, with his near-miss at his home race in 2008 one of the most memorable moments in F1 history.

"I have nothing to worry about, I'm an accomplished guy and that's the most important. I actually had a lot more than I imagined in my career, I fulfilled all my dreams."

Though ending his time in F1, Massa, who competed in 269 races with 11 wins and 41 podiums, has no intention of stopping racing and long being linked to a future seat in Formula E.

"I have some talks with some teams, with some people but everything is in the very beginning," he commented. "There is nothing that I can say that is close, but it will appear quickly."

What is known is he will take a role as the Head of the FIA's Commision of International Karting.
