Jenson Button may have a first win under his belt but he admits his love affair with his McLaren is yet to fully blossom.

Upon arriving at the team, Button was always aware it would take a certain amount of time to become accustomed to a new order, and in particular to develop an affinity with his car. But after his victory in Australia on Sunday, he at least now knows he has a race-winning car beneath him going into the Malaysian Grand Prix on Sunday.

"I've spoken before about needing time to get more comfortable in the car, and I still mean that," said Button. "There's still a little way to go until I think I'll find the new environment completely suited to me."

He added: "At Sepang, which is an awesome circuit and one I love driving, I think I'll be able to further develop and improve my relationship with the car.

"It's a circuit that not only requires smooth and precise input, but it also needs real commitment through some of the high-speed stuff."

It is also a circuit where Button won last year, achieving back-to -back victories for the first time in his career, albeit in the wet as storms brought an early finish and only half points.

More of the same is expected this weekend, but after the highs of Melbourne, nothing can rain on Button's parade right now.

He continued: "It underlines that not only are we competitive, but we're very well integrated, that as a team we can trust and rely on each other and we can build on those strengths.

"That's what I'm most excited about, the impetus that this will give us.

"The fact we've already got one win under our belts, and we can clearly see the work ahead of us that we want to do to be better, then that's really, really encouraging."
