Jenson Button says the Belgian GP represents McLaren's best chance yet of a podium

Jenson Button reckons next month's Belgian Grand Prix represents his and McLaren's best chance yet of finishing on the podium this season.

McLaren took a risk with the design of their MP4-28 in the hope that it would enable them to out-develop rivals. Instead, its lack of performance has meant they've had to backpedal - which, as Button explained, has left the Woking team playing catch-up. "We've completely changed the car aerodynamically. It's a completely different philosophy now, it's back to the idea that we had last year and the idea that most of the pitlane have," he said. "It was bringing the airflow over the top of the sidepod to the rear end of the car, where you have the rear wing and the floor - where you really need the downforce. "Now, if you look at the car, the sidepods cut in more trying to get the clean air to the rear of the car. It's working well but the development is behind the other teams. "But I do feel we're catching up. We're finding things all the time." McLaren might be out of the running for this year's World Championship but, according to Button, each new aero part they add has relevance for the 2014 season, even though the rules then will be different. "They're very different, in that the downforce we'll have is a lot less than what we have now. But the ideas we have this year could still help us next year," he added.
