Celtic usually arrive at this kind of fixture expected to control the ball, pin the opposition back and turn territory into pressure. That does not make it simple.
These are the afternoons when selection matters. Fresh legs in wide areas, a creative midfield choice or a more direct centre-forward can alter the pattern before a ball is kicked. Reports may carry projected line-ups, but the confirmed team sheet often tells the real story.
When Rangers play on the same day as Celtic, the emotional context is unavoidable. Even before kick-off, the pressure is to keep pace and avoid leaving any opening for scrutiny.
This is where live coverage becomes more than a scoreboard. Supporters track substitutions, shape changes and any hint of nerves as much as the result itself.
In Scotland, weekends like this can sharpen the whole season. One favourite dropping points, one outsider growing in belief, one unexpected team selection - that is how the narrative shifts.
The next thing to watch is simple: whether Celtic and Rangers handle the expectation cleanly, or whether St Johnstone and St Mirren can turn a standard Premiership day into something far messier.
