"As a driver when you join a team you need to be innovative, have lots of ideas, to have the initiative to keep on pushing the team and asking questions," he said.

"That's the bit I love about this job, so when it comes to the race and all of that comes together and you win, it's one of the best feelings.

"But I've got so much belief. I really do believe in my team and my abilities, and I've no doubts we can do it.

"Although it's easier said than done, I think this weekend we've a good shot."

Hamilton said his third-place finish last time out in Barcelona, behind the Ferraris of Raikkonen and Felipe Massa, showed signs of improvement.

"Over the course of that weekend we became faster and faster, and then in the race we were again quicker," he said.

"The great thing is we were able to push (Ferrari) at the end, which I wouldn't say was a relief, but it was a confidence boost for the whole team, including myself."
