Felipe Massa may have retired from Formula 1 at the end of last season but the Brazilian reckons he could put in a 16th campaign come 2018.
Massa quit Formula 1 after the 2016 season but his retirement was short-lived as Williams brought him back to partner rookie driver Lance Stroll following Valtteri Bottas' move to Mercedes.
And it has been a good comeback for the 36-year-old.
With two sixth-place finishes to his name, he is holding down seventh place in the Drivers' standings and reckons he could yet stick around in 2018.
"Unfortunately I’m not leading the championship but I’m still there, fighting and doing well," Massa told Reuters.
"I am 100 percent concentrated on this season but… if I can race still at a good level for a good team, then I can do another year.
"If I feel comfortable if I feel that I am doing a good job, and I am important for so many people as well, why not? I feel fit; I am fitter now than in all of my years in Formula One," he added, burnishing his credentials.
"I didn't know how I was going to be in this car so for sure I was training really, really hard and trying also to get a little bit more muscles and I feel really great."
He added: "I feel I’m doing well, I like the new rules and the new car, the way you are driving.
"It's something that also is better for my driving style that I feel really comfortable. We just did three races but I think we're doing a good job."
