Felipe Massa had a simple message as he prepared for the Spanish grand prix - I'm not worried.

The paddock rumour mill is whispering loudly about the Ferrari-themed future of his current Williams teammate Valtteri Bottas.

Former Ferrari driver Massa, on the other hand, is hoping he will stay at Grove for another year.

It is believed Massa, 34, signed a two-year contract when he arrived last season, with the team able to trigger a further one-year 'option' this July.

"I see no reason to worry about the future," the 11-time grand prix winner told Brazil's Globo in Barcelona.

"I also see no reason for Williams to think about changing something. So I am calm."

Massa also insisted he is not worried that Williams' resurgence appears now to be coming to an end, after it was overtaken by Ferrari so far in 2015.

Not only that, the hugely-resourced Red Bull team has arrived in Barcelona with a big upgrade package, and also making rapid progress is the McLaren-Honda giant.

"With what we have, we are doing a great job," Massa said.

"If you are not on the right track with a lower budget, then you have a serious problem. But the proof that Williams is on the right track is that we are the team that has signed the most new sponsors," he insisted.
