A rejuvenated Felipe Massa says he is pleased by his switch to Williams ahead of the season opening Australian Grand Prix.
Massa has moved to Williams after spending the previous eight years of his career with Ferrari.
"I think it's a new time, like a re-start - for me but also for Williams," he told Sky Sports News.
"I think it's the right time to change; it's the right time to have a new team, a team that really wants to get competitive again and really wants to get back to the top.
"I'm really enjoying working with Williams for the moment. There's still a lot to do and a lot to learn and understand but I'm really looking forwards. I hope we can have a competitive season, a good car and trying to put Williams on the top again."
Massa's team-mate, Valtteri Bottas, added a note of caution but believes the team is in a stronger position compared to 2013.
"This season the starting point for us is a lot better than last year," he said.
"The team is really starting to go in the right direction and we are getting to where we belong. But we are keeping our feet on the ground - testing is only testing and racing is racing, there are no points for testing. So let's see, Melbourne is coming soon and then we will see where we are."
