Pure wild speculation on my part but with McLaren signing Norris and Sainz for next year, one suspects Alonso would only return to F1 now for one final roll of the dice with Ferrari or Renault, his previous teams.
Could anyone see that happening or was there bad blood at the end of their relationship that would mean it’s just not gonna happen? For example if Vettel called it time, would they turn to an Alonso?
