The Hoops fell behind to an early Jonny Hayes strike before Stuart Armstrong's leveller and Australian global Tom Rogic's dramatic stoppage time strike sealed only the fourth domestic treble in the club's 129-year history.
Jock Stein (1967-68), Tommy Burns (1995-96), Martin O'Neill (2001-02) and Neil Lennon (2013-14) all came agonisingly close to unbeaten league seasons with Celtic, each losing just one league game.

Superintendent Mark Hargreaves, Match Commander for the event, said: "We have reviewed the security plans for the Cup Final along with our partners at the Scottish Football Association and it will be appropriately resourced to ensure people attend and leave the event safely".
And in a week which saw the Parkhead club celebrate with gusto the winning of the European Cup in Lisbon 50 years ago, excitement levels are rising ahead of what would be an historic achievement at Hampden Park today (kick-off: 16.00).
