Carlos Sainz says it's decision time for his F1 future amid Williams and Sauber-Audi 2025 interest

Carlos Sainz says it is "time to make a decision" about his Formula 1 future - but admits he has not yet decided who he wants to drive for.

The Spaniard, who found out in February that he had lost his Ferrari seat to Lewis Hamilton for next season, is thought to be mulling over offers from Williams and Sauber, who will be under the full control of Audi ahead of a rebrand in 2026.

While Sainz said he had no news to share on the eve of his home Spanish GP, he admitted that the time had come for him to imminently decide on who he was going to sign for.

"The latest is a decision will be taken very soon," said Sainz

"I don't want to wait any longer. It's getting to a point where it's taking space out of my head for quite a few weeks and months now.

"It's time to make a decision and the decision will be taken soon. Hopefully soon we will have things to talk about."

Although the three-time race winner is highly regarded in F1, Sainz's options for 2025 have seemingly distilled into a choice between two teams currently well down the grid, albeit Williams and Sauber each have big hopes of making major progress up the field in future seasons.

Red Bull opted to retain Sergio Perez as Max Verstappen's team-mate on what was announced as an extended two-year term, while Mercedes look poised to replace Hamilton with 17-year-old rising F2 star Andrea Kimi Antonelli.

Asked if he knew in his own mind here where he wanted to drive, Sainz replied: "No. I'm still not sure one way or another.

"It's still something I am discussing with my team and brainstorming. I need a couple of days back at home.

"I've been at home before this weekend but I had my head in the Spanish Grand Prix. It's been a hectic two weeks after Canada for me, so I haven't had time to sit down and take a decision. This is what I will target in the next few weeks."

Williams' public appeal for Sainz

Sainz is the key component in the driver market as his future will dictate where other drivers go in 2025 as eight other drivers have not confirmed they will be on the grid next year.

At first, it looked like he would join Sauber, which will become Audi in 2026, but Williams have emerged as a serious option for the Spaniard and James Vowles made a public appeal for Sainz at the Canadian Grand Prix earlier this month.

"Sainz is our No 1 target," Williams boss Vowles told Sky Sports F1.

"There's a reason why I left Mercedes to come here. This isn't the Williams of old. Having Sainz on our list shows we are prepared to have a driver line-up that I think will be one of the best on the grid, if it's achieved.

"We are investing tens, if not hundreds of millions back to where it was in terms of success. In the background, there were a number of really great signings that will slowly start edging out in the next few weeks and months."
