O'Neill confirmed as Celtic's permanent manager

Celtic have confirmed Martin O'Neill as their permanent manager after his interim spell last season ended with a Scottish Premiership title and Scottish Cup win.

The appointment turns a short-term return into a longer-term role for O'Neill, who stepped in twice during the 2025-26 campaign before being handed the job full time. Reporting on Thursday said he has agreed a one-year deal, with an option for a further year.

The move gives Celtic a settled direction after a turbulent succession period and comes with preseason planning and the next transfer window approaching.

A successful interim spell

O'Neill's return to the dugout proved effective almost immediately. He guided Celtic to domestic success after being brought in on an interim basis, and the club's league-and-cup double last season ultimately changed the shape of the managerial search.

BBC Sport reported on June 11, 2026, that Celtic had confirmed the permanent appointment.

The Guardian said the deal is for one year with an option for another, while other reporting said the confirmation was made through a stock exchange announcement and on Celtic's website.

Board backing and transfer plans

The appointment was backed by Celtic's principal shareholder Dermot Desmond, who said O'Neill would have support in the transfer market, according to reporting.

That backing matters because the club is now trying to turn a successful emergency intervention into a more stable structure around the first team.

O'Neill arrives with considerable institutional knowledge and a strong record at Celtic. The Guardian reported that he has won nine major honours across his spells with the club.

The manager himself struck an ambitious tone, saying he was hungry for more success at Celtic.

Backroom uncertainty

One unresolved question is the make-up of O'Neill's backroom staff. Reporting said the futures of assistants Shaun Maloney and Mark Fotheringham remain uncertain.

That leaves Celtic with a new permanent manager but not yet a fully settled coaching structure around him.

The staffing question is likely to be watched closely because it will shape how quickly the club can move from a successful short-term fix to a longer-term football operation.

How the appointment evolved

O'Neill's return also follows a broader managerial process that had not been straightforward. Reporting said Robbie Keane had previously been considered for the role, but that route collapsed amid fan backlash.

Against that backdrop, Celtic have opted for a familiar figure who already delivered on the pitch during the most recent campaign.

The appointment also reflects the pressure on the club's leadership to settle on a clear direction after a period of uncertainty at the top of the football operation.

What happens next

The immediate focus now shifts to preseason work and squad planning.

Celtic are expected to use the coming weeks to clarify the coaching set-up, define the manager's operational role and continue work on transfer-market backing.

For O'Neill, the task is straightforward in outline but demanding in practice: build on an unexpectedly successful interim spell and turn it into sustained progress.

The permanence of the appointment gives Celtic a defined manager heading into the next phase, but the final shape of the staff around him is still to be settled.
