Carlos Sainz recently reflected on what could be one of the proudest moments of his F1 career ahead of the 2025 season.

The former Red Bull Racing Junior driver, who joined Atlassian Williams Racing after leaving Scuderia Ferrari at the end of the 2024 season, admitted that securing a podium finish with his current team would be one of the proudest moments of his career.

“I’m in my 10th year in Formula 1, and I’m joining Williams at a very important moment, as the team is undergoing key changes in its history. Nothing would make me happier or prouder. It would definitely be the proudest moment of my career if one day I can stand on a podium with this team,” Sainz was quoted as saying by Motorsport Week.

Williams Racing last recorded a podium finish at the 2021 Belgian Grand Prix, when George Russell finished second in a rain-affected race.

Prior to that, the Grove-based team’s last podium came at the 2017 Azerbaijan Grand Prix, when Lance Stroll recorded a third-place finish in his rookie season with the team in Baku.

The Grand Prix could have ended even better for the Canadian, as a last-lap overtake by Mercedes-AMG's Valtteri Bottas saw what could have been a second-place finish for Stroll reduced to third.

Whether Sainz can achieve this feat during the 2025 season remains to be seen. However, judging by early signs, the Spanish driver cannot be ruled out, especially considering he set the fastest time during the three-day pre-season test at the Bahrain International Circuit.

The four-time Grand Prix winner could well be one of the dark horses of the 2025 F1 season.
