The Australian netted the fourth goal of the emphatic win in the 47th minute, marking his eighth goal of the campaign in all competitions.

Rogic's strike also improved his remarkable record against Rangers, having netted in three Old Firms in the past month and a half.

The ball fell kindly for Rogic on the edge of the box after Rangers keeper Jak Alnwick had saved from Callum McGregor.

With Alnwick out of position following his save, Rogic curled in a left-foot shot into the unguarded net for 4-0.

Odsonne Edouard netted a first-half double, while James Forrest and McGregor also hit the scoresheet in the win as Celtic were crowned SPL champions for the seventh season in a row.
