It depends on how much JCF actually did. Its only JCF who has lost his job the rest of the team is still there. So its not like its a complete overhaul. The assistant/second coach who filled in for JCF before can handle the reigns till they either promote him hire a new coach or work alongside a short term consultant like Ferrer or Moya till after the AO.
Notable disagreements between Ferrero and Alcaraz’s father over the management of the player’s career were the main reason behind the split.
