Logan Sargeant has credited team-mate Alex Albon for Williams' success during this past Formula 1 campaign.
The Grove-based squad ended the season seventh in the Constructors' Championship to take its highest result since the 2017 campaign.
All but one of its 28 points came from Albon as Sargeant took a solitary point at the United States Grand Prix.
The American driver was unable to match Albon's performance throughout the campaign and was involved in a series of incidents that placed his future under question.
However, Williams recently confirmed that Sargeant will remain at the Grove-based squad for next season alongside Albon.
Reflecting on Williams' run to P7 in the standings, Sargeant told media including RacingNews365.com: “It means a lot to me.
“I did the best I could to make sure we held that. Alex has done a phenomenal job all year, he's majorly to thank for that.
“I think Alex has been superseding this year. We haven't always had a car that's easy to score points and Alex was always just a little bit ahead to make sure he was there to score them.”

Sargeant notes personal improvement
Sargeant was the only driver in the field to be out-qualified by his team-mate at every single round this year.
However, the 22-year-old is confident that he enjoyed an upturn in pace in the second half of the campaign.
“I don't think it's always been as bad as it looks, especially since the summer break,” he said. “I'm proud of the way I kept fighting through the whole year.
“The progress I've been making through the year has been really, really nice for me to see and hopefully I can contribute more in the future.
“The team has done great with the car this year, I think speaks even more volumes that we only brought one upgrade to the car the whole season.
“To do what we did was strong, and we can be proud of that. And hopefully, the car will be another step forward next year.”
