Prost banks on Rosberg

It's not much of a high risk bet at this stage, but four-time world champion Alain Prost is putting his money on Nico Rosberg to win this year's world title.

Speaking to French broadcaster Canal Plus, Prost reiterated his belief that Rosberg will keep Lewis Hamilton at bay until the end of the season thanks to his current 33-point lead.

"A 33 point lead starts to be important," said Prost.

"It's much better to have that lead with four races to go than the four wins he had at the start of the season.

"He will have to manage this lead now, and get into a psychological state that is not always easy."

Prost insisted however that it could still all go wrong for the German: should he suffer a retirement in Austin, Hamilton will be back in the chase.

"It's never easy to manage such a big lead, especially against Lewis Hamilton, who thinks the whole world is against him now. But it could still turn, one retirement and Lewis is right back in the race."

Noting Rosberg's nine victories this season, Prost reminded everyone that no driver has ever won as many races and failed to win the title.

"How can you not be champion if you've won nine races? That is the question Nico Rosberg hopes he does not have to answer at the end of the season.

"But the German is doing everything he has to for his first world title."

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
