Martin O'Neill becomes Celtic's permanent manager after successful interim role

Martin O'Neill has officially agreed to a permanent managerial role at Celtic, signing an initial one-year deal on June 5, 2026. The 74-year-old previously led the club to a domestic double after taking over as interim manager, winning the Scottish Premiership and Scottish Cup. His appointment follows discussions with major shareholder Dermot Desmond and comes after a tumultuous managerial search that included talks with Robbie Keane. O'Neill first took charge in October 2025, amid a crisis at the club, and quickly turned around their fortunes by securing key victories down the stretch of the season.
