Ahead of a much-needed summer rebuild, Celtic will be looking to appoint the right individual for the challenge, and a host of high-profile candidates have been linked with the position over the past few months.
Here's a look at OddsChecker's top twenty contenders to become Celtic's next manager, as the race starts to heat up:
17. Roberto Martinez - Current odds: 7/1
He's done a stellar job with Belgium, but could be tempted back into club management in the near future. His team finished in third place in the 2018 World Cup. Photo: IAN WALTON
18. Frank Lampard - Current odds: 5/1
A run of dismal results saw Chelsea owner Roman Abramovich dismiss the Blues icon earlier this season. He secured a top-four finish in the 2019/20 campaign, despite being unable to sign new players due to the club's transfer ban. Photo: IAN WALTON
19. Eddie Howe - Current odds: 9/4
He'd be a popular choice for the job, that's for sure. The charismatic coach took the Cherries all the way from League Two to the Premier League, and at the age of 43, he's still got plenty of years left in him. Photo: Dan Mullan
20. John Kennedy - Current odds: 6/4
The interim manager is currently the bookies' favourite to become the next permanent Celtic boss. During his playing career, he was capped once at senior level for Scotland. Photo: Ian MacNicol
