It has to be Brendan Rodgers, doesn't it?
No, wait what about Kjetil Knutsen, Graham Potter, or Pep Guardiola's assistant Enzo Maresca?
Is Davie Moyes now in with a shout of a return to Paradise after guiding West Ham to a Europa Conference League trophy?
The betting on the Northern Irishman was suspended at one point earlier this week with the former Liverpool and Leicester boss still the bookies' favourite to seal a return to Celtic Park for a second stint as manager.
Would Rodgers be welcome back to Celtic with open arms?
The Celtic managerial hunt is now in full swing and the names being linked with the vacant post are changing on an hourly basis, or so it would appear.

The latest is a shock contender in the shape of AZ Alkmaar boss Pascal Jansen. Jansen is reportedly on the list of names that Parkhead hierarchy is considering as a replacement for Ange Postecoglou.
The London-born boss is fresh off the back of leading AZ Alkmaar to fourth in the Eredivisie.
His side was also knocked out of the Europa Conference League by eventual winners West Ham at the semi-final stage. Jansen, like Postecoglou, is well known for his attractive style of football but has never held a job in British football before.
The 50-year-old is a wanted man as Ajax and PSV are also reputed to be interested in Jansen as they seek permanent replacements for Alfred Schreuder and Ruud van Nistelrooy respectively.
Meanwhile, Spanish outlet Estadio Deportivo claims that Andoni Iraola, who turned down Leeds during the season, could be the man to join the Hoops.
He recently quit Rayo Vallecano having guided them to a comfortable mid-table La Liga finish.
However, Italian media source Il Seculo XIX reports that Franceso Farioli is also on the radar of the Scottish champions.
Former Rangers striker Ally McCoist reckons that the chances of Moyes opting to leave West Ham for Celtic are now up in the air after the Hammers' 2-1 Europa Conference League final win against Fiorentina in Prague.
Moyes became only the seventh Scottish manager to win a European competition but his future with the London club was seemingly unclear as he has only got one year left on his current deal.
McCoist believes Moyes will stay put and speaking on talkSPORT, he said: "No, he'll stay where he is. He's just won a European trophy man."
