Motorsport: Rubens forecasts world title with Ferrari

RUBENS BARRICHELLO is convinced he will be world champion within three years after tying his future to Ferrari until the end of 2006.

The 31-year-old Brazilian has agreed a two-year extension to his contract which will bring him in line with team-mate Michael Schumacher.

"I expect to win races and fulfil my dream, winning a world championship at least one," said Barrichello.
