In 2023, before Brendan Rodgers was appointed as manager, the other managers shortlisted included:
Jesse Marsch
Now manager of the Canadian international team, he has a contract which runs until after the 2026 World Cup (hosted in the USA & Canad) and is unlikely to leave before then. He took Canada to a 3rd place finish in the CONCACAF Nations League Finals recently.
John Kennedy
Long time assistant and ex-player John Kennedy was caretaker briefly in 2021, and has now been assistant to four managers (including Brendan Rodgers twice).
Enzo Maresca
When Celtic were last looking for a manager, Maresca was assistant manager at Man City. However, since then he has stepped up into managerial roles, guiding Leicester to promotion before joining Chelsea and winning the Conference League title.
David Moyes
Ex-Celtic player Moyes was linked to Celtic in 2023 with things going badly at West Ham. He left in 2024, but has successfully returned to management at Everton, guiding them to a safe 13th place finish last season while West Ham have struggled under replacement Graham Potter.
