Fans packed the ground to see Callum McGregor lift the cinch Premiership trophy after Ange Postecoglou’s side wrested the silverware back from Rangers, a success confirmed in midweek at Dundee United.
That left a title procession set for the sunshine in the east end of Glasgow where Motherwell were the visitors who themselves were hoping to secure a fourth-placed finish and two fewer European qualifiers next season.
It wasn't to be as Celtic celebrated in style. As a prelude to the party Ange Postecoglou tried to give it appropriate build-up with a strong line-up, and his team repaid their manager and turned in an impressive display that had the fans on their feet long before the trophy was shown off.
Here’s how Ange Postecoglou's team rated.

6. Callum McGregor - 8
Smothered by Motherwell’s midfield at every early opportunity and when eventually working free in the lead-up to half-time, Celtic’s attacks developed an incisive edge. Roamed free in the second half and dictated the play. Photo: Jane Barlow
7. Jota - 8
It could have been his final game too - Celtic fans hope not - but Portuguese was quiet to start then came alive in the second half. Almost laying on two goals before taking care of his own and Celtic’s fourth in a dynamic second 45. Photo: Craig Foy - SNS Group
8. Tom Rogic - 7
Said goodbye to Celtic Park as a winner in an emotional afternoon but no goal or typically late runs for popular midfielder. Replaced to standing ovation by James McCarthy. Photo: Craig Williamson - SNS Group
