Leading bookmaker Coral has made John Kennedy their odds-on favourite to become Celtic's manager on a permanent basis.
The assistant boss has been handed the reins after Neil Lennon's resignation was announced on Wednesday morning.
The 37-year-old has worked under Ronny Deila, Brendan Rodgers and the Irishman as he has developed a strong reputation with the club's power brokers.
He's priced at 4-6 with former Bournemouth manager Eddie Howe considered the next most likely to head up next season's rebuild at 4-1.
Scotland boss Steve Clarke is available at 6-1, Frank Lampard is 7-1, while Rafael Benitez is 8-1.
Coral's John Hill said: "John Kennedy has the chance to try and earn the Celtic job on a full time basis and we make him the odds-on favourite to do that.
"There are some big names behind Kennedy in the betting for this job, including Eddie Howe, Frank Lampard and Rafael Benitez," added Hill.
Legendary striker Henrik Larsson, currently and assistant coach to Ronald Koeman at Barcelona is also on the list at 25-1.
Full list of runners and riders: 4-6 John Kennedy, 4-1 Eddie Howe, 6-1 Steve Clarke, 7-1 Frank Lampard, 8-1 Rafael Benitez, 12-1 Roy Keane, 20-1 Thierry Henry, 25-1 David Wagner, 25-1 Henrik Larsson
