Carlos Sainz acknowledges that expectations for Williams in 2025 are modest, but insists the team is not lacking motivation as it works toward long-term success.
The Spaniard, who spent the past four seasons forming a strong partnership with Charles Leclerc at Ferrari, found himself without a seat after the Scuderia signed seven-time world champion Lewis Hamilton for 2025.
When asked about Hamilton's prospects at Ferrari, Sainz remained diplomatic.
"I was never his teammate, so I don't know what he is capable of," he said. "I have never seen his data.
"I know how good Charles is, but I can't say the same about Lewis. When I look at his background and his results, I can only say that there's a very good chance that he will be competitive in the Ferrari. But that always depends on how well he can get used to the car and the team.
"There are so many factors that play a role that it is impossible for me to make any predictions."
Sainz made it clear that he would have preferred to stay with Ferrari.
"I remember saying to all the people at Ferrari when I left that they are ready to fight for championships and even win a title this year. When I left, the team was at full throttle, in great shape to go for that challenge.
"And I know that Charles is ready to fight for a championship," he said.
With Red Bull and Mercedes turning him down, Sainz ultimately chose Williams after being convinced by team principal James Vowles' vision for the future. However, Williams finished ninth in the 2024 standings, and Vowles has been upfront about prioritising long-term development over short-term success.
"I think the team is keeping it low at the moment," Sainz told Spanish journalists when asked about his expectations for 2025.
"It doesn't mean we're flat or anything. I think it means the team knows this year is a transition year for 2026.
"That is a year where the team wants to take a big step forward.
On the other hand, 2025, well, I know we've made progress and I think the team is showing that progress, but how much of that progress can allow you to fight for a podium? I think it's, honestly speaking, relatively unlikely, but hey, you never know.
"I prefer to be more optimistic and wait at least for the test or the first race to see where we are."
