Celtic are reportedly eyeing a move to appoint former Chelsea, West Ham, and Brighton manager Graham Potter to replace Martin O'Neill in the summer, according to Football Insider.
Potter has amassed plenty of experience in English football during his career, starting in the Premier League with Brighton before moving to Chelsea. The now-Swedish national team manager was then appointed as West Ham boss, but he was sacked earlier in the 2025/2026 season.
Potter most recently took over the Swedish national team with a view to helping them qualify for the World Cup. As it stands, his contract expires after the qualifying campaign, meaning he could be a free agent in the coming months.
Sweden may look to keep him on if he qualifies, but there's still every chance he's available in the summer after the tournament.

According to a report from Football Insider, Celtic are eyeing a possible move to appoint former West Ham manager Potter in the summer. O'Neill's current deal at Celtic expires at the end of the season, and the Glasgow giants are already working on possible replacements.
An update on Potter's situation with the Swedish national team is believed to be close, which could rule him out of the running or boost Celtic's chance of bringing him to Parkhead.
Potter will likely be fully focused on the task in hand with Sweden at the moment, but you'd imagine he will be keen on a return to club management in the near future.
Whether a move to Scotland would be of interest to the 50-year-old remains to be seen.
O'Neill Needs to Improve Fast

It's unclear if O'Neill would be keen on landing the Celtic job on a permanent basis, but if he does, he needs to start showing signs of improvement. The Bhoys were recently defeated 2-1 at home to Hibernian, while they also dented their chances of advancing in the Europa League after suffering a 4-1 loss at home to Stuttgart a few days prior.
Some of Celtic's wins of late have been a struggle, too, needing last-minute winners against Kilmarnock and Livingston.
It appears Celtic are willing to make a change, but winning the Scottish Premiership title would do O'Neill no harm.
