On an afternoon in which the nuptials of a young couple dominated worldwide headlines, it seemed only fitting that Celtic’s performance at Hampden should call to mind the words of one of the great English Romantic poets, John Keats.

As Callum McGregor’s goal burst the net, Keats’ line about ‘a thing of beauty is a joy forever….it will never pass into nothingness,’ seemed particularly prescient. Of course, the Hoops support had its own little ditty about just where the Royal wedding could go; their day at Hampden was a celebration of the success of its own marriage.

The relationship between Brendan Rodgers and the support has never had cause to leave the honeymoon period. 13,000 supporters turned up in the sunshine of a Monday evening in June to open the door to him almost two years ago and it is a coupling that has since provided unending pleasure.

If they are throwing garlands at Rodgers now, history will place him in a very particular context at Celtic after becoming the first manager to secure back-to-back trebles.

Rodgers’ has now presided over six out of six in terms of the silverware on offer to him, a feat that eluded some of the great names who have stood in the Celtic dugout.

Jock Stein was robbed of it by a dodgy call otherwise he’s have claimed it first and there will be plenty who will line up to cast aspersions on the quality of opposition that Rodgers is up against. But while there has been a drop in performance levels over the course of this season, what jumps out from this Celtic team is that they can be trusted to turn up when the occasion demands.

McGregor’s goal, while the game was still in its infancy, effectively set the seal on Celtic’s back-to-back-treble for if Motherwell were to have stood any chance in Saturday’s game they had to take first blood.

But for McGregor himself and for the club as a whole, the goal, the game, the result will forever be framed within the context of Rodgers’ opening two seasons at the club. It was Rodgers in a nutshell when he walked into his post-match press conference at Hampden and gave first voice to the potential of a treble treble, but first things first.

His own drive will ensure that he doesn’t dine out for long on this weekend’s frolics but at the same time all concerned ought to take time to digest the achievements of this season; Rodgers explained only recently that he enjoyed last season’s treble until day 3 of his holiday when a fear or what would come next had him organising his thoughts.

There will be little time before the nervy qualifiers to secure Champions League football get underway again and the pressing demands of another 60-odd game season await. Players will leave the club this summer and there is a need to refresh the squad, but for now they have earned an entitlement to stand and take a look at the view.

Hampden and Celtic have not always been easy bedfellows.

And yet of all the iconic moments the Parkhead side have enjoyed in the Mount Florida stadium, McGregor’s goal deserved to be up there alongside them. It didn’t have the drama of Tom Rogic’s winner in monsoon conditions a year ago as the Australian stroked the ball into the net against a bolt of lightning to seal a domestic Treble.

Nor did it have the desperate, aching need of Pierre Van Hooijdonk’s 1995 Scottish Cup winner which ended a six-year drought without any silverware. It wasn’t Davie Provan’s free-kick and Frank McGarvey’s diving header in 1985 or a Frank McAvennie centenary winner, but it was a goal that confirmed Celtic’s place in history and added a significant chapter to the club’s story.

By the time Olivier Ntcham added a second with a raking drive into the net, there was never going to be any way back for a Fir Park side who looked off the pace and unable to cope with the pace and tempo with which Celtic moved the ball.

Of all the Parkhead players who deserved to take their bow in such circumstances, few would begrudge McGregor his moment. As various players were quoted this term for individual awards, McGregor’s name seemed to slip under the radar and yet his performances, particularly in the latter half of the season, have been notable.

McGregor’s right-footed, half-volley was of the eye-catching variety in sharp contrast to a player whose contribution is significantly understated.

Like Rodgers’ team, McGregor has grown into a position whereby he can be trusted to deliver on the biggest of stages as his goals this season have shown.

With Celtic and Rodgers insisting that there will be no let-up, there is every chance that there will be further opportunities to showcase that particular ability.

For now, though, there is the right to drink it all on as they raise a toast to a marriage in full bloom.
