The Grove squad is the clear backmarker this season, and is lacking roughly over a second in pace to its nearest rival. Head, who helped Sir Frank Williams establish the team in the late 70s, has remained a shareholder despite leaving the team earlier this decade.
Head stepped down as Williams' technical director in 2012, after holding the position for 27 years. Williams confirmed that "Head is currently offering some support to our engineering team on a short-term consultancy basis.”
Williams last won a race at the 2012 Spanish Grand Prix, and took a handful of podiums throughout the turbo hybrid era.
However after a difficult 2018 season saw it slump to the bottom of the standings, it looks set for the same feat this year.
