Sunday’s table-topping clash with Hearts is a fixture that carries huge meaning for both clubs

It is instructive that Thursday evening’s Europa League clash in Bologna could be regarded by Celtic as an inconvenience. Aberdeen hold the Scottish Cup. St Mirren claimed the League Cup in December. Celtic find themselves involved in a title race worthy of the name. In short, domestic dominance is no longer a guarantee.

Much has been said – and screamed – about the flow of poor decision-making that at least has Celtic’s hitherto immovable position in Scotland under threat. There has also been wild exaggeration in respect of the current crop of Celtic and Rangers players being among the worst in living memory. Celtic finished fourth and adrift of Motherwell in successive seasons from 1993. Rangers rattled around unconvincingly in the lower divisions, including a failed attempt to win promotion from the second tier, after their financial meltdown of 2012. The relative weakness of others in Scotland’s top flight is a reasonable point for debate but Old Firm fans have encountered much, much worse than this.
