The Bhoys went for Ronny Deila in the end. But what if...?
As Ronny Deila approaches the end of his first full season at Celtic, all is well at Parkhead.
A first domestic treble since 2001 *could* be on the cards. Champions League failure was cushioned by an admirable Europa League effort against Inter Milan and, more importantly, things look set for the long term at the Scottish champions.
But what if things had gone differently last summer? Namely, what if the Bhoys had hired Roy Keane?
The Irishman was quoted as saying by BBC Sport that he was unimpressed by Celtic's offer to manage them last summer and the Hoops eventually turned to Deila.
And, whether Keane ever ends up at Parkhead in the future, they'll be thankful they went for the Norwegian on this occasion.
Despite a slow start and mixed messages in his opening few months, Deila has, as stated, delivered a real sense that there is a long-term strategy at Celtic. The Norwegian often appears unconcerned with short-term results and is more interested in progress and development.
Would Keane be? His managerial record so far certainly wouldn't suggest so - and that's without even looking at his overall lack of success.
When Scott Brown was pictured slumped after a night out before the Scottish League Cup final, meanwhile, how would Keane have reacted? How would he have responded to Anthony Stokes returning late from holiday?
Celtic's current manager has made a big deal of dealing with player mistakes with praise or constructive criticism. It's never been about that with Keane.
There are also a number of young, promising talents at Celtic that seem to respond well to Deila. How would they respond to Keane let alone vice versa? And what about the media - who are greeted with openness and honesty right now as opposed to being told coldly to switch off their mobile phones (!)
The biggest question of all, however, is probably whether Keane would still be at Parkhead had he taken the manager's job. Deila most certainly is and looks like he will be for a while.
