McLaren's Jenson Button was philosophical after a slow final pit stop cost him the chance to challenge for the win today in China.

Button was looking well placed to take the fight to race long leader, Nico Rosberg, and was comfortably on course for second at the Shanghai Internataionl Circuit until his third and last stop on lap 39. A problem with the left rear though cost the Englishman crucial time and when he rejoined he dropped back behind a gaggle of cars running line-a-stern in second.

Although he did eventually haul himself back up to P2, by then any hope of taking the win was gone.

Despite that though, the 2009 F1 World Champion, was still pretty pleased with his afternoon and he now lies second in the drivers' championship, just two points behind team-mate, Lewis Hamilton.

"Congratulations to Nico on the win - he drove a faultless race. But who knows what we could have achieved if we'd had a clear run at him in the final stint?" Button pondered.

"Our pace was very good and the aim was to come out ahead of that following pack of cars - which we would have done if we hadn't lost time in the pitstop - and chase him down and put him under pressure.

"The delay in the final stop was just one of those things though - all the other stops had been very strong this weekend, but that one in particular wasn't. The delay pushed me back into the traffic, which was a little bit of a shock, but the pace and consistency are there in the car and I was able to get back into second position, after a good battle and a satisfying pass on Sebastian [Vettel].

"It's disappointing not to have been able to challenge for the win, but it was a fun race with tons of overtaking and lots of battling. More important, it's been a great day for Vodafone McLaren Mercedes because we're now leading both world championships.

"It's very important to be consistent, and it's nice to be back on the podium, but there are just a couple of little things we need to improve upon to make life even better for ourselves."
