Martin O’Neill said it was a “great privilege” to be confirmed as Celtic’s permanent manager for a second time and vowed that the club will not rest on the success of last season.
The 74-year-old’s two interim spells in charge resulted in an unlikely Premiership and Scottish Cup double at the end of a season of unrest at Parkhead.
He has agreed a one-year contract with the option for a further year after talks with Celtic’s major shareholder Dermot Desmond.
And despite claiming his eight and ninth trophies as Celtic manager in 2025-26, O’Neill suggested he expects a busy summer of action to improve a squad that trailed Heart of Midlothian for most of the season.
O’Neill’s sentiment was backed up by interim chairman Brian Wilson and principal shareholder Dermot Desmond.
“It is a great privilege for me to continue as Celtic manager,” O’Neill told the club’s website.
“Last season will live long in all our memories and to be part of that success has in a big way whetted the appetite to work again for more days like those and bring our supporters those moments.
“I would particularly like to thank the board for giving me this opportunity.
“Celtic can never rest on past success so we are aiming to drive forward together and deliver again for the club and our fans.
“I thank our fans for their ongoing support, it means everything. I look forward to being back at Celtic Park, when we will come together and strive to bring our fans the success which that support deserves.”
Wilson said the appointment was “the start of a busy summer” where the club “will ensure we are in the best possible position to compete”.
