The first domino in the Formula One driver market has fallen with Aston Martin's confirmation that Fernando Alonso will be driving for the team in 2023.

Sebastian Vettel's retirement announcement ahead of the Hungarian Grand Prix was always going to lead to movement on the grid but Alonso's move from Alpine is a significant statement of intent from the Silverstone-based team.

Alpine are currently vying for the best of the rest tag in 2022, alongside McLaren, while it has been a year to forget so far for Aston Martin – but they still boast one of the most recognisable brands on the grid and Alonso is a stellar acquisition.

There will be further movement, with a number of teams yet to confirm their full driver line-up for the 2023 season – with Alpine, Haas, Alfa Romeo, AlphaTauri having one spot open, while Williams have not confirmed either driver.

That leaves six seats up for grabs as it stands, with some of the outcomes easier to analyse than others – Alonso's departure from Alpine solves their headache as it leaves a slot open for reserve driver Oscar Piastri.

The Australian was already heavily tipped to take a seat on the grid for 2023 but, with Esteban Ocon and Alonso at Alpine, just where that spot would open was up for debate, with a Williams move touted, but it should now be a fairly easy decision.

For Williams, it could result in the continuation of their partnership with Mercedes. With Alex Albon expected to retain his seat, a replacement for Nicolas Latifi is on the agenda and the leading option may now be Nyck de Vries.

Toto Wolff had already conceded that De Vries, who is on their young driver programme, could be let go in order for him to open avenues in F1, but a seat becoming available at Williams would be perfect for all parties – potentially lining-up De Vries as Lewis Hamilton's long-term successor.

Another option for Williams is Jamie Chadwick, who has dominated the W series and has her eyes set on a seat in F1, though she has expressed doubt as to whether women can cope with the physical demands of the series.

Seats at Haas, Alfa Romeo and AlphaTauri are harder to assess but Mick Schumacher could play a pivotal role for the trio. Yet to be confirmed by Haas for 2023, the young Ferrari driver could make a sidewards move to continue his F1 career.

Given AlphaTauri's relationship with Red Bull, Alfa Romeo seems the more likely option for Schumacher if he was to depart Haas and an opportunity to drive alongside Valtteri Bottas could aid his development – though Alfa Romeo have a young talent of their own waiting in the wings in the form of Theo Pourchaire.

Felipe Drugovich, the runaway leader in F2 this season, and American Logan Sargeant are alternative options within the young driver ranks, while both have additional appeal due to their respective nationalities, Brazil and the United States, both of which are areas of growth for F1.

The break period in the F1 season is usually the time where teams line everything up for the next year, so the next few weeks before the season resumes in Belgium are likely to be extremely busy – and there could be some surprises in store.
