Any cup meeting between these two sides is inevitably presaged by a recap of those ubiquitous upsets in 2000 and 2003, but for the second year running Celtic produced the kind of efficient, muscular performance in a cup match at Inverness which suggests we all might have to look elsewhere for our reference points. It saw the Scottish Cup holders glide serenely into the last eight, and moved their winning domestic run in all competitions on to the 15 mark, with a treble looking a more realistic possibility with each passing week.
