Alonso is currently weighing up whether or not he wants to remain in F1 beyond the end of this year, when his current contract runs out.
He says his priority is to stick with Aston Martin, but he has also been linked with potential drives at Red Bull and Mercedes if certain scenarios open up.

While the Spaniard has said he is more than happy at the team since he joined Aston Martin at the start of 2023, the squad has been battling in the middle of the chasing pack behind Red Bull this year rather than at the front of it as it was for a spell last season.
That has left team principal Mike Krack convinced the Silverstone-based outfit needs to up its game and push up the grid if it is to guarantee Alonso wants to remain.
"We need to add more, we definitely need to add more," said Krack. "But I think if he can fight and not be in the middle of nowhere, it's already a first step. And then we will not stop.
"We will bring parts over the season to keep him motivated and keep him happy at Aston Martin."
