Title 'completely open' - Button

Button says he is still in the thick of the title race

Reigning world champion Jenson Button says he thinks the title race is still wide open, despite lying fifth in the standings with four races left.

The next race is in Japan, where McLaren driver Button has never won a race, but he said he felt confident.

"Obviously there's no room for mistakes but any of the top five drivers could easily steal the title," he said.

"It might seem a disadvantage to be behind in the standings but make no mistake, I know I can win this title."

With four races left in the season, Button has 177 points, 25 fewer than championship leader, Red Bull driver Mark Webber.

Ferrari's Fernando Alonso is second, with McLaren's Lewis Hamilton third and Red Bull's Sebastian Vettel fourth, four points ahead of Button.
