Ocon and Alpine marriage stranded: Where can the Frenchman go now?

It was an announcement that had been in the air for several days: Esteban Ocon is leaving Alpine after the current season. Although there was no mention of it in Alpine's press release, the unnecessary clash with teammate Pierre Gasly at the Monaco Grand Prix must have been the straw for the French team: Gasly and Ocon together in one team is not possible, and therefore one has to leave. Ocon, who had been slowly making himself impossible to stay, must therefore look for a new employer. Where can he go now?
