Gordon Strachan's side clinched a hat-trick of championships thanks to a 1-0 victory against Dundee United at Tannadice, while rivals and long-time favourites Rangers were beaten 2-0 at Aberdeen.

The Old Firm rivals had been level on points at the start of Thursday evening, with Celtic holding the goal-difference advantage.

Each match was goalless at half-time, however Aberdeen took the lead through Lee Miller against Rangers after 63 minutes to give the first indication of where the trophy was destined.

Striker Jan Vennegoor of Hesselink then headed Celtic ahead after 72 minutes at Tannadice to leave little doubt, and Aberdeen's second goal at Pittodrie from Darren Mackie after 77 minutes ended Rangers' hopes.

Substitute Nacho Novo was sent off for a two-footed lunge on Aberdeen's Stuart Duff as the Gers saw their hopes of a domestic treble shattered.
