Last week, Celtic confirmed that manager Ronny Deila will leave the club this summer, as his rolling contract will not be extended.
The Norwegian arrived from Stromsgodset in 2014, and whilst he won the Scottish League Cup and Premiership last season, his second term in Glagsow hasn't been quite so successful.
The Bhoys will still edge towards the title in unconvincing fashion, but Deila oversaw disastrous exits from the Champions League and Europa League, but the Scottish Cup defeat to Old Frim rivals Rangers - currently in the second tier - has seen Deila lose his job.
Fans are already wondering who could replace Deila this summer, and bookmakers have been pricing up odds for some of the frontrunners. With odds supplied by Oddschecker, here are some of the main names being discussed today...
Gordon Strachan: The former Celtic boss is currently in charge of the Scottish national team, but is being mentioned for a shock return to Celtic Park. In four years at Bhoys manager, the 59-year-old won three league titles, one Scottish Cup and two Scottish League Cups, and is now down to just 8/1 to become Celtic manager again.
Roy Keane: Keane made 13 appearances for Celtic at the end of his career, and has long been touted for the job despite disappointing spells with Sunderland and Ipswich Town. Now Martin O'Neill's assistant with the Republic of Ireland national team, Keane could look for a return to management - and at 9/2, the Manchester United legend could be right in contention.
Steve Clarke: A surprise name to emerge in the last 24 hours is Clarke. The former Chelsea and Liverpool coach had hit-and-miss spells in charge of West Brom and Reading, and the Scot left the latter in December. Now possibly looking for a route back into management, the 52-year-old is now 5/2 for the Celtic job, making him one of the favourites.
Alex Neil: The Norwich City boss may end up suffering relegation from the Premier League this summer, and less than 18 months after leaving Hamilton Academical, he could be approached for a return to Scotland. The 34-year-old has earned a great reputation as a bright young manager, and at 10/1 he could be a dark horse for the Celtic job.
The favourite - David Moyes: Unsurprisingly, the favourite is former Celtic defender Moyes. Looking to rebuild his career after poor spells with Manchester United and Real Sociedad, the Scot is the odds-on favourite and would be the choice of many fans given his reputation and previous success in the Premier League.
