Ange Postecoglou guided Celtic to the cinch Premiership title at the first time of asking despite drawing 1-1 at Dundee United.
The Hoops, who went into the game six points ahead of reigning champions Rangers with two games to play, took a 53rd-minute lead through Giorgos Giakoumakis' 15th goal of the season.
However, they were forced to make do with a 1-1 draw at Tannadice when United, who had twice hit the post in the aftermath of the opening goal, levelled courtesy of Dylan Levitt's piledriver.
