Williams delays driver announcement to January

40

Williams has pushed back to next month the announcement of its 2018 driver line-up, but Sergey Sirotkin remains the team's most likely choice.

The Russian's surprise presence with Williams and subsequent good performance at last month's post-season Abu Dhabi tyre test has put the 22-year-old in pole position for a drive also targeted by Robert Kubica.

Kubica camp still fighting for Williams drive

Based on performance alone, the Pole was apparently told by Williams' management that he was no longer a contender for the 2018 seat alongside Lance Stroll.

But Kubica's father, Arthur Kubica, insists his son and his management team are still fighting for a deal with the Grove-based outfit.

Reports indicate that Williams is in the process of finalising Sirotkin's contract, with both parties now focused on minor details and the preparation of a formal announcement scheduled for after the new year.

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.
