Rangers and Celtic meet on Sunday in the first Old Firm derby of the Clydesdale Bank Premier League season.
That is not the only first of the weekend though.
It will be the first Old Firm match Ally McCoist and Neil Lennon have faced off against each other in the manager’s position, with the former the understudy of Walter Smith at Rangers before being awarded the top post himself.
The pair certainly have history.
Each is loyal to their club through and through, and both angrily reacted towards the other at the end of the last Rangers v Celtic encounter back in March.
This match at Ibrox will be an interesting barometer for the destination of the SPL title, with the Scottish league trophy almost certainly headed to Glasgow.
We may find ourselves a bit closer to knowing if it will be to the blue or green half on Sunday evening.
