What happened: Celtic have confirmed Martin O'Neill as their permanent manager on a one-year contract with an option for an additional year. The 74-year-old returned for two interim spells during a turbulent 2025-26 season, ultimately guiding the Hoops to the Scottish Premiership title and a Scottish Cup victory.

Why it matters: The appointment provides stability following a campaign that saw three different managers at the helm. O'Neill successfully overturned a six-point league deficit in January and delivered his ninth major trophy at Celtic with a 3-1 win over Dunfermline in the Scottish Cup final.

What to watch: O'Neill is expected to oversee a significant squad rebuild this summer as Celtic prepares for the Champions League group stage.
