Carlos Sainz has signed a contract with Williams, which means that we only have 4 free seats left.
Those who do not yet have a driver line-up for next year are: Sauber, Alpine, Mercedes and VCARB
Sauber - for a long time it was speculated that Sainz would go to Sauber because the team will change to Audi and his father has contacts in Audi, also because he won the Dakar with Audi this year. The team offered him a lot of money, but from the beginning we can expect the Audi to drive even worse than the Williams themselves. The future with Zhou is uncertain, and Bottas is also not completely certain. Another option is Zane Maloney, who is racing in F2 with the Sauber academy and has solid results this season. So we will have to wait and see who will sit next to Hulkenberg.
Alpine- Alpine will leave Esteban Ocon, who found angasm at Haas. Will Pierre Gasly stay in the team and who will be next to him? One possibility is Mick Schumacher who drives for Alpine in the WEC series, another reason is that he is supposed to switch to Mercedes engines, Mick is also a Mercedes reserve driver, so it would make sense. Another choice is Jack Doohan, who is currently driving in F2, where he has good results and is also in the Alpine academy, and he also drove in free practice at the Canadian GP.
Mercedes- Sainz was also a possibility for Mercedes, but he would stay there for a maximum of 1 year and the next would be replaced by Kimi Antonelli, but since Sainz is already confirmed at Williams, we can expect to see Kimi at Mercedes next year. He is currently driving in F2, where he performs well. But we can't rule out Verstappen, who is also being speculated about, because Redbull is no longer so dominant and with the upcoming new rules, where Redbull will develop its own power units, it would make sense.
VCARB- Ricciardo's contract expires at the end of this season and of course he is trying to get a place at Redbull instead of Perez, who has not been doing very well lately, although it might have seemed that he could take his place at Redbull after the summer break, but that is not the case, christian Horner denied these speculations and confirmed that Perez will stay at least until the end of the season.
