The Bhoys confirmed the 52-year-old - who managed the Scottish club from 2016 to 2019, and then again since 2023 - had left his position as their head coach late on Monday (27.10.25), following Celtic’s 3-1 defeat to Hearts on Sunday (26.10.25).
In a statement, Celtic said: “Celtic Football Club can confirm that football manager Brendan Rodgers has today tendered his resignation. It has been accepted by the Club and Brendan will leave his role with immediate effect.
“The Club appreciates Brendan’s contribution to Celtic during his two very successful periods at the Club.
“Brendan leaves Celtic with our thanks for the role he has played during a period of continued success for the Club and we wish him further success in the future.
“The process to appoint a new permanent manager is underway and the Club will update supporters further on this as soon as possible.”
The club confirmed former Celtic manager Martin O’Neill, 73, and ex-player Shaun Maloney, 42, would be taking temporary charge of The Bhoys.
Celtic continued: “We are pleased that during this interim period former Celtic manager, Martin O’Neill and former Celtic player, Shaun Maloney have agreed to take charge of Celtic first-team matters. Further details will be confirmed shortly.”
Rodgers had been put under pressure following Celtic’s loss to Hearts, which had placed them eight points behind the leaders in the Scottish Premiership.
After being announced as Celtic’s interim manager, O’Neill admitted he was “shocked” Rodgers had stepped down.
He told talkSPORT: “I got a call late afternoon, early evening yesterday from Celtic from Dermot Desmond, and Dermot asked me would I step in because Brendan had resigned from the football club.
“It’s obviously the kind of shock news really as much as anything else. Shocked me as well too.
“But just to step into the breach and just do it on a short-term basis until a permanent manager is appointed.”
When asked whether he was apprehensive about taking the job as Celtic’s temporary boss, he O’Neill said: “Like everything else, I took a gasp of breath and thought, is this real or surreal?
“It’s difficult really to turn down somebody who gave you the job in the first place when he had really some great options a way back 25 years ago.
“So from that viewpoint, maybe by the time that I pulled myself off the floor, I probably thought then maybe I should do it.
“I think they were probably stunned by the news that Brendan left and as a consequence, they maybe might be obviously seeking a permanent manager.”
