For just over 17 years the two men have been the driving force at Celtic, surviving through good and bad, some horrendous managerial appointments and a number of minor issues that could have led to a parting of the ways.
Since Fergus McCann sold up in 1999 Desmond has been the biggest single shareholder but has been very reluctant to get hands-on, happy to take a distant, sometimes detached view as Lawwell called the shots and strengthened his power base within the club.
A run of disastrous results has put Neil Lennon under severe criticism with an increased focus on the two men who have overseen the current collapse in results, confidence and almost certainly transfer vale of the squad.
Over the last eight days Celtic have issued two statements backing Lennon but it seems that behind the scenes all isn’t well at the top of the club.
Until now, Mr Desmond’s assessment of his CEO is that he is good for the bottom line. He only broke with that view when he was personally abused at Hampden in April 2016.
An EPL level manager then guided the Scottish champions to an unparalleled era of domestic domination. Of course, you know how it ended.
I stated at the start of this historic season that then the only thing that would stop Celtic is Celtic and so it has proved to be. If my information is correct, then the relationship between the CEO and the main shareholder has effectively broken down.
