Veteran F1 commentator Murray Walker says his "fingers are crossed" for Jenson Button who is on target to win this year's drivers' championship. Button, 29, stands on the brink of championship glory, knowing he needs six points from the Brazilian Grand Prix to become the 10th Briton to claim motor sport's greatest prize. Walker says he would like to see the Brawn GP driver get the podium place he needs in Brazil: "I'm English and I naturally want an Englishman to win. "I would like to see Jenson win the world championship and he's in a very strong position to do so." Speaking at the launch of Microsoft's new Forza Motorsport 3 game, Walker also spoke of his disgust at the recent race-fixing controversy: "I was shocked, disgusted, apalled, outraged, all the strongest possible words you can use because that was without precedent in the history of Formula One." The 86-year-old says he now hopes everyone can move on and look forward to "some real racing" at the final two Grand Prix events. Button is currently 14 points ahead of his teammate Rubens Barrichello who leads Red Bull's Sebastien Vettel by 2 points.
