Former driver Ralf Schumacher anticipates that Carlos Sainz's next Formula 1 move will be disclosed "this week."

Before the Spanish GP in his home country this weekend, the Ferrari exitee shared with the local Antena 3 broadcaster that he found it hard to accept the news of his 2025 replacement by Lewis Hamilton.

"Obviously you don't take it well," said Sainz. "No one likes being left behind, no?

"I had very good years at Ferrari, I started the year very well, but a seven-time world champion wanted to come and they made room for him. But I also see it as an opportunity for the future, because I still want to be world champion."

The major rumour in the paddock is that Sainz has already signed a deal with Williams, finalised last time out in Canada.

"If the rumours are to be believed, Sainz has signed with Williams and that will be announced this week," former F1 driver Schumacher told Sky Deutschland.

"Sainz at Williams may sound strange at first, but the team has big goals and ambitious investors. And to be honest, it was the best option for him."

Speaking on the Antena 3 program El Hormiguero, 29-year-old Sainz stated that he will reveal his decision for 2025 and beyond "very soon."

He has also been closely associated with Audi-owned Sauber.

"I have my options on the table, ready to make a decision, and I will make it very soon because I want to get it over with and focus on the rest of the year with Ferrari," said Sainz.

"All the teams that have not signed their drivers at the moment have offered me a contract and I can sign with them tomorrow," he claims. "But I'm going to take it a little calmly, even if I'm going to decide soon."
