Aye, but like I said in my other post - it's 20+ years for us now. But given we have beaten Celtic multiple times in those 2 decades, there must be more to it.
And I still think a large part of it is because Rangers tend to be much more phyiscal, whereas Celtic tend to play more football - and we always perform better against the latter. (And it's no coincidence we beat Rangers in the cup semi when we had our full contingent of hammer throwers in the team).
