Felipe Massa has said that he is unfazed by speculation that Jenson Button could replace him at Williams next year.

Button, now 36, made his Formula 1 debut as a teenager in 2000 and now rumours suggest that he could end his career at the Grove team, replacing Massa from 2017.

However, the Briton, who currently drives for McLaren-Honda, is not commenting.

"I haven't even thought about the next race in Canada, let alone the next year," Speed Week quoted him as saying recently.

As for Massa, the 35-year-old - who in turn is being linked with a move to Renault - said that the Button rumours are not bothering him.

"We all know about rumours in Formula 1, and I am zero scared and worried about anything," he is quoted as saying by The Express.

"It would be nice to stay, but it would be nice to stay in a team where you really see that you can do a good job and have a good future. I am ready for everything."

It is believed that McLaren's decision to replace Button with Belgian Stoffel Vandoorne has essentially already been taken, although boss Eric Boullier denies that.

"No, we have not started negotiating with any driver," he is quoted as saying by Speed Week. "It is still far too early for this question, which would be a distraction for the team."

The 2016 championship continues this weekend with the Canadian Grand Prix.
