Jenson Button, McLaren, Chinese GPWorld Champion Jenson Button has labeled his Chinese Grand Prix win the best victory of his career. The Briton kept his cool in the tricky conditions and, thanks to making the right calls, Button took his second win of the season and with it the championship lead.

Button lead McLaren teammate Lewis Hamilton to the team's first one-two finish since the 2007 season.

"For me, it is my best victory -- every one you win becomes your best victory, but this was was pretty tough conditions," said Button. "The good thing is our pace was very good today. It wasn't just the call of weather, it was good pace. At the end we were two seconds a lap quicker than other people. We will don't know where we are in the dry, but we will forget about it at the moment."

Button, who had also made a bright call to win the Australian Grand Prix last month, said today's victory had nothing to do with luck.

"It is not luck we came out on top today," he said. "We chose correctly in the conditions. The start was the right call definitely but it was slippery and we knew how quickly the soft tires would be working. It was the right call. My first few months with the team have been extraordinary. I feel a real part of the team now."

Button said his decision to stay out on slicks early on was crucial, as it was the safety car being deployed.

"Really important, it made the race," he said. "If we didn't have the safety car later in the race for debris we would have been a long way up. The safety car definitely helped the situation for those who stopped for inters.

"Staying on dries was the right thing, you wouldn't think it was, but they were good, you just had to be a bit careful. Definitely the right call and then when the team called me in the lap was the right call. The tyres had started graining so it was too wet for slicks."

Team boss Martin Whitmarsh said the team had made the right calls for both drivers, and that their driving had been the difference.

"Fantastic job by both drivers," said Whitmarsh of Button and Hamilton. "They obviously had different strategies, but they ran the race just great. It was tense, those last laps, but they were racing, they were going for it. They were quicker than everyone else in those conditions. We took that as our view of how to go racing, but boy did it make a long race for us.

"Lewis had a fantastic race -- again, so many overtaking moves. Jenson was a little bit lighter on his tires. We played the right strategy for both cars."
