No one yet knows for certain who will be the next permanent Celtic manager, and there has been no official announcement beyond the current arrangement with Martin O’Neill for the rest of the 2025–26 season.

What’s officially known

  • Celtic have confirmed that Martin O’Neill has returned as manager for the remainder of the 2025–26 season after Wilfried Nancy’s dismissal.
  • At this stage, the club have not publicly named a successor beyond that timescale, so any specific “next Celtic manager” call is speculation rather than fact.

Names linked and reported targets

  • Some reporting suggests Celtic view Roberto MartĂ­nez as a top target for the next permanent manager, potentially after his 2026 World Cup commitments.
  • Fan and media discussion also revisits experienced figures like O’Neill himself and other winning coaches with European pedigree, but these are suggestions rather than confirmed negotiations.

Fan and forum discussion vibe

  • Supporters on forums and fan media are debating whether the next Celtic manager should be:
    • A proven European-level coach.
    • A progressive, modern tactician in the Ange Postecoglou mould.
    • Or a “Celtic-minded” figure with strong club ties.
  • There is also talk about how Dermot Desmond’s network and the current board dynamics shape the shortlist, with some fans expecting another left‑field appointment similar to Postecoglou or Ronny Deila.

Realistic outlook

  • In January 2026 the most grounded line is:
    • Current manager : Martin O’Neill to end of 2025–26.
* **Strong rumour/target** : Roberto Martínez viewed as a leading candidate post‑World Cup 2026, but not agreed or confirmed.
  • Until Celtic issue a formal statement, “who will be the next Celtic manager” remains an open, trending topic rather than a question with a definite answer.
