This was an occasion when Celtic could reflect on and celebrate their Scottish Premier League campaign. Yet it was also a day in which glances towards the future were unavoidable, specifically in the context of Neil Lennon.
Celtic's manager addressed his supporters after collecting the SPL trophy, with a promise to "see you all at the cup final" included in Lennon's message. What occurs beyond that depends as much on decisions on Merseyside as in Glasgow, with Lennon quoted among the favourites for the managerial position at Everton.
Lennon's future aside, summer intrigue will surround the movements of key Celtic players including Victor Wanyama, Gary Hooper and Fraser Forster. If this marked goodbye for some to Celtic Park, it was done with a lap of honour, families by sides and a tone of celebration, albeit not an exuberant one. There has always been an element of inevitability, after all, about Celtic's second title in succession.
"These are days you want to cherish," Lennon said. "It is important that the players appreciate what they have done because it goes by very quickly. I am proud that we have proved we are not a flash in the pan team." Of the notion that the SPL is far easier minus Rangers, Lennon said: "In essence there is something to that but we have a job to do, a responsibility to win trophies; that is part of the DNA here, as is doing it in a certain way."
There should be no surprise attached to the fact Lennon is not acting like a man who will have new employers by the time next season kicks off. He will spend Sunday watching players with a view to improving his Celtic squad. Still, it seems highly improbable that Lennon would spurn the opportunity to take over at Goodison Park were the position to be offered to him. For all the Northern Irishman rightly speaks of Celtic's allure and size, there is a mundane element to domestic football in Scotland which is unavoidable.
It is also wise for any manager, or player, to take forward steps when their stock is high rather than risking stagnation. Lennon's appeal to Everton is clear. He has a record of sourcing players for relatively little money and increasing their value significantly.
Celtic's Champions League performances traised the stock of Lennon and his players beyond what any achievement in Scotland could do. What cannot be ignored is that Lennon lacks the experience of managing in England, and the Premier League, which others in Everton's thoughts do have.
Lennon's most immediate aim is to endorse Celtic's vast superiority at home by securing a double. Hibernian are their opponents for the Scottish Cup final in a fortnight; if St Johnstone were shown a glimpse of Celtic's May mood then the Edinburgh side will have to wait a little longer to end a 113-year wait to lift the old trophy. With their captain, Scott Brown, back in the team for the first time since mid-February, Celtic all-but settled this game by half-time. Joe Ledley claimed the opener from 20 yards after James Forrest had played the ball back into his path. St Johnstone had a legitimate grievance over a handball by Hooper earlier in the buildup but the visitors were hampered, too, by Thomas Scobbie botching an attempted clearance.
Charlie Mulgrew's free-kick looked to take a flick off Patrick Cregg before bouncing past Alan Mannus for Celtic's second. Anthony Stokes, dubiously, claimed a headed touch when the goal clearly appeared to be Mulgrew's.
A surging Hooper run and pass to Forrest triggered No3. The young winger, who will be an important cup final player in the expanses of Hampden Park, supplied a low and angled finish. Forrest should have scored again, but blazed over following some wonderful build-up play from Stokes. As both Georgios Samaras and fellow striker Hooper passed up glorious chances, it seemed Celtic's scoring for the afternoon was over.
That proved untrue as the St Johnstone defender Frazer Wright scored an own goal when he diverted the ball past Mannus from another Mulgrew set play. Wright, indeed, was fortunate to last 90 minutes after an off-the-ball whack on Mikael Lustig.
