What happened: Celtic have confirmed the permanent appointment of 74-year-old Martin O'Neill as manager on a one-year deal. The move follows a highly successful interim period where O'Neill led the club to both the Scottish Premiership title and the Scottish Cup trophy.

Why it matters: The appointment stabilizes the club following the mid-season departure of Brendan Rodgers and a brief tenure by Wilfried Nancy. O'Neill's return has unified a fanbase that previously voiced significant opposition to other candidates, ensuring continuity for the defending champions.

What to watch: O'Neill will now focus on the 2026-27 campaign and the club's upcoming European commitments as they look to build on their domestic dominance.
