A hat-trick by Scott Sinclair helpedCeltic to secure their sixth successive Premiership title in a commanding 5-0 win against Hearts at Tynecastle.
The league challenge started in Gorgie last August as Brendan Rodgers kicked off with a 2-1 win courtesy of a late debut goal by Sinclair after he had come off the bench.
Moussa Dembélé and Leigh Griffiths were out with respective hamstring and back injuries for the return to Edinburgh but the former Manchester City and Aston Villa forward rendered their absence irrelevant with two well-taken goals in three first-half minutes.
Stuart Armstrong added a third with a drive and Patrick Roberts scored a wonderful fourth before Sinclair notched his third from the spot with seven minutes remaining.
It was a championship wrapped up in style for Celtic, who are unbeaten in 30 league games since the start of the season, winning 28 and drawing two, and the club remain on course for the Treble.
Hearts had started the game encouragingly enough but could not recover from Sinclair’s early double and they remain two points behind fourth-placed St Johnstone.
For a fixture which is rarely short of incident and talking points, the first one of the afternoon was the absence of Dembélé and Griffiths. The winger Roberts replaced the former as the main striker while Hearts also showed one change with the midfielder Perry Kitchen taking over from Arnaud Djoum.
The Celtic midfielder Callum McGregor was offside when he converted a Sinclair pass in the first minute of a frantic first half. The Hearts striker Esmael Goncalves drew a fine save from the former Hearts goalkeeper Craig Gordon in the 10th minute with a powerful drive from the edge of the box, before thwarting the same player minutes later after he had been set up by Jamie Walker. The visitors raced up the other end and McGregor tamely side-footed a pinpoint Sinclair cross past the post from eight yards.
Hearts looked the more likely to score and Gordon had to punch clear a Krystian Nowak header from Walker’s corner but a moment of magic in the 24th minute turned the game in Celtic’s favour.
A classic one-two between Sinclair and Roberts inside the box ended with the latter driving high past the helpless goalkeeper Jack Hamilton.
Three minutes later Sinclair was released through the middle by Roberts and he raced clear to knock the ball past Hamilton for his fifth goal against Hearts this season and his 20th in all competitions.
There seemed little belief among those in maroon, summed up early in the second half when the striker Bjorn Johnsen blasted a shot high over the bar when he had options. Moments later, at the other end, the winger James Forrest’s shot was deflected in by the Hearts defender Tasos Avlonitis but the offside flag was up.
However, there was no mistaking the validity of Armstrong’s goal in the 55th minute as the in-form midfielder, who made his Scotland debut against Slovenia last Sunday, drove in from the edge of the box after taking a pass from Kieran Tierney.
The 1,476 Celtic fans behind the goal stepped their celebrations up further when Roberts curled in the fourth with his left foot from just inside the box after being slipped in by McGregor.
As some of the home fans in the crowd of 16,539 began to drift away, the champions kept pressing for a fifth goal. And when Nowak was adjudged by the referee Kevin Clancy to have tripped Sinclair inside the box, the Celtic forward slammed the penalty high past Hamilton to complete a memorable afternoon for him and the rampant visitors.
