Video: Claire Williams underlines Massa's crucial role this year

Felipe Massa went through a revolving door this winter, retiring from the sport before jumping back in after Valtteri Bottas' move to Mercedes.

Williams apparently made the 35-year-old Brazilian an offer he couldn't refused, premised on the fact that the Grove-based outfit required a fast and experienced driver to handle a season of change and development with the introduction of F1's new rules.

In the video below, Claire Williams underscore Massa's role of lead driver this season, with expectations running high.

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.
