CELTIC clinched the Premiership title after a Giorgos Giakoumakis goal sealed a 1-1 draw with Dundee United at Tannadice.
It caps a superb first season in Scotland for Ange Postecoglou, who delivered the crown back to Parkhead at the first time of asking.
A litany of former Celts took to social media to congratulate the team, including club legend Kenny Dalglish. The Scotland record-holder had a classy message for Postecoglou and even quoted the Celtic Song.
He posted: "Congratulations to Celtic FC. Not bad for your first season, Ange. Sure it was a Grand Old Team to play for..."
