In doing so, he has demonstrated something about both why he got the manager's job in the first place and why it proved to be too big for him.
I dare say that if I had been given a lucrative, high-profile job which I was poorly qualified for, I might also feel inclined to defend the person who put my improbable progress ahead of the club's.
But one of the features of Celtic in recent years has been the fawning to the corporate strategy of a succession of coaches, even when players were foisted upon them or sold from under them against their wishes.
Ronny, like the others, is unlikely to burn his bridges in terms of a possible return but while there have been inklings of dissatisfaction when each coach going back to, and including, Martin O'Neill have left, these have quickly been airbrushed away in a disconcerting manner.
Can you manage Celtic without being prepared to kiss Peter's ass? It's not clear that you can and there is suspicion that contract clauses to that effect have been signed.
But Ronny also shows that he has never yet got to grips with the expectations Celtic fans have.
Despite the usual claims from PLC fans, acolytes and online shills, few, if any, Celtic supporters want the club to “spend money we don't have” - we just want players signed on the basis of what they can contribute to the team, rather than the balance sheet.
Is it really too much to want to see good players playing good football and an improving team? Is it unrealistic to want to keep the good ones for a few seasons, instead of selling them at the first opportunity, while we get to keep the crocks, the bottlers, the bad boys, layabouts and other assorted dross?
Shouldn't we want players and teams to become legends, rather than recalling them primarily for their plus-or-minus contribution to the profit-and-loss statement?
Does Ronny think we don't deserve better, that we just aren't as smart as Peter?
Perhaps he also thinks we are wrong not to have meekly accepted being cheated out of titles and Champions League participation, the acknowledgement of the fact of Rangers being liquidated and the innumerable flagrant rule breaches which Peter has remained silent on, if not actually being complicit.
Under Peter Lawwell's period of tenure, most of the values that have made Celtic special have been erased and, worse, the fans who wanted them upheld have been mocked and derided by the PLC/Lawwell camp.
Ronny Deila is a nice and good man, who should not be condemned for genuine loyalty.
At the same time, he should not seek to lecture Celtic fans on issues that we understand rather better than he does.
We - and generations before us - are the ones who have sustained Celtic and made the club great. Ronny's two years of service do not qualify him to dismiss our concern at the decline of Celtic and declare Peter's way to be the only way.
Ronny Deila is entitled to speak for himself and still contracted to speak for Celtic PLC. He need not think that he speaks for the fans.--
