If the hairdryer treatment still exists in football dressing rooms, it is difficult to envisage it coming from the mouth of Brendan Rodgers. There is little that passes from the Celtic manager’s mouth that is not measured and controlled.

For Leigh Griffiths, then, it may be time to take swift lessons in commonsense. Not for the first time yesterday at Lennoxtown, Rodgers delivered something of a rebuke to the striker that was laced with genuine affection.

That the Parkhead manager rates the player for what he can do on a football pitch is not in question. And yet no-one will hinder Griffiths’ chances at Celtic more than Griffiths himself.

Tying a scarf to a post in a volatile opposition ground is creeping close to becoming the favoured party piece from the Scotland striker. Inevitably it is well received amongst his own, particularly on an evening when those around him were keen to lob his head off with a glass bottle, but given that his manager seeks to present a polished image of respect and tolerance, such antics are never going to be well received by the diplomatic Rodgers.

Six months ago the Celtic manager went public – twice in the space of a few days – when he insisted that Griffiths needed to get his act together off the field. His patience was snapped with a run of niggling injuries that he attributed to the player not looking after himself properly away from the watchful eyes at Lennoxtown. The days of tunnocks tea cakes already felt like a long time ago.

In fairness to Griffiths, he took it on board. Even before he put those free-kicks past Joe Hart at Hampden, Griffiths has put in a performance against England in June that suggested a growing awareness of his position, a maturation in the way he plays, much of which goes down to his own work on the training ground and much, too, goes down to the advice given out from Rodgers and his coaching staff.

It is fair to say that Rodgers himself might have been among those who was surprised by the way Griffiths was able to lead the line for Scotland against England. And while the anticipation was that Moussa Dembele would pop back into the starting line-up at the beginning of the season after his injury issues last term, it was Griffiths who was handed the jersey for the opening competitive game against Linfield last Friday night.

He does himself no favours now by looking at an enforced ban now for the next qualifier. And if tying scarves to wind up supporters doesn’t go down well in the eyes of his manager, it most certainly won’t be well received by the suits, hypocritical or not, at UEFA. At the very least he can anticipate a one game suspension but his problem is not being straitjacketed for 90 minutes in the stand, but the potential of not getting back in once he is out.

Griffiths has value to Celtic but it is not sitting in a stand.
