Cape Town - Valtteri Bottas has said he is going to be in for a "difficult year" trying to beat Lewis Hamilton, but believes he can.
"He's a great driver and a champion and I haven't won a race so in theory the odds are for him. But I know what I'm capable of in a winning car."
Bottas has been given a one-year deal by Mercedes, but the Finn wants to do everything in his power to extend his stay with the Silver Arrows.
He said: "We have both been keen on sharing data. There are no issues with that. We have been very open, both ways. Our meetings have been very productive."
