The fight for this year's Formula One world title is effectively a two-man battle after Rubens Barrichello led home a Brawn GP one-two at the Italian Grand Prix.

In taking his second win of the season and 11th of his career, the 37-year-old Brazilian has now closed the gap on team-mate and championship leader Jenson Button down to 14 points.

With Mark Webber crashing out on the opening lap and Sebastian Vettel claiming a solitary point, the Red Bull duo are 26 and 28.5 points adrift of Button with four races remaining.

Lewis Hamilton should have joined Barrichello and Button on the podium, only to dramatically crash out on the final lap at Monza as the reigning world champion chased down his fellow Briton.

With Hamilton 53 points behind Button, it means his reign is at an end, with nothing but pride to race for in Singapore, Japan, Brazil and Abu Dhabi.
