Tom Rogic scored in stoppage time as Celtic beat Aberdeen 2-1 in the Scottish Cup final to complete a historic unbeaten Treble.
The Dons took an early lead when Jonny Hayes swept the ball past Craig Gordon following a corner but Stuart Armstrong quickly equalised for Brendan Rodgers' men with a fine finish from outside the box.
Both teams had chances in a thrilling final but Celtic's late pressure paid off when Tom Rogic, on as a substitute, drove the ball beyond Joe Lewis to seal a memorable victory.
It is the first time since 2000/01 under Martin O'Neill that Celtic have claimed a domestic clean sweep - they also did so twice in the 1960s when Jock Stein was in charge but never before without losing a single match.
