Celtic swept Rangers aside 4-0 in the first Old Firm clash of the season to open up a five-point lead at the top of the Scottish Premiership.
An early injury to in-form striker Kyogo Furuhashi did not phase the champions as Liel Abada fired them ahead soon after.
Jota showed a lovely piece of skill to make it 2-0 with Abada on target again as Celtic raced into a 3-0 half-time lead.

A mistake by Rangers goalkeeper Jon McLaughlin then allowed substitute David Turnbull to make it 4-0 as Giovanni van Bronckhorst once again failed to lead his team to a league victory over their rivals.
The win maintains Celtic’s 100 per cent record in the Scottish Premiership this season with 25 goals scored so far.
Can Celtic be stopped?
Postecoglou stayed with the same starting XI that romped to a 9-0 victory at Dundee United in their last Scottish Premiership match.
Alfredo Morelos returned to the Rangers squad after being dropped for disciplinary reasons, but started on the bench with Antonio Colak remaining in the starting XI.
