The season had morphed into an all-out brawl between Williams-BMW and Ferrari. Barrichello’s victory at the season finale, in Japan, secured Ferrari’s record fifth straight constructors title. The BMW-powered rivals won again in France and with three races left, Williams-BMW was leading in constructors points. In the decisive play-off against Tunisia, they were defeated 4-1 in Tunis and won 4-2 at home, therefore being eliminated. Still, there are some numbers that are universally agreed upon being used for a particular position, because they are quintessentially associated with that role. Cuéllar was never at risk of losing his job despite dubious results, and he even hired close allies, including his son Christopher Cuéllar.
