Former Formula 1 driver Ralf Schumacher didn't hold back on his criticism of a team boss after a disappointing start to the 2024 season.
The German driver spent six seasons with Williams Racing in the early 2000s, racking up six wins and 21 podium finishes. But since the team's last title win in 1997, Williams have fallen a long way from grace.
Boasting the second-highest number of constructors' championships (nine) behind only Ferrari, Williams' struggles to recapture their former glory have been well documented.
The disappointment has continued in 2024, with the team languishing at the bottom of the constructors' standings.
Both drivers, Alexander Albon and Logan Sargeant, were retained for 2024. Yet, despite the continuity, results have been abysmal.
Currently sitting a lowly eighth with zero points, Williams are one of only three teams yet to score this season, alongside Alpine and Stake F1.
What's more, a lack of preparedness has led to a situation that every F1 team boss fears. Williams were only able to run one car in Australia having not had a spare chassis to replace the one that was wrecked by Albon during practice.
Another huge smash for Albon at the Japanese Grand Prix led to concerns that they may once again have to run just the single car in China this weekend, with the team confirming that the chassis had indeed been badly damaged once again.
Both Williams' lack of performance and preparedness has drawn criticism from Schumacher, who seems to be questioning Vowles' ability to turn things around.
"I think [Vowles] has to look after himself a bit now," the former race-winning driver said to Sky Sports Germany.
"I wouldn't be surprised that he's not necessarily on [Williams] owner's bestseller list."
