The galling thing for Rangers is that a Celtic performance no better than moderate in level was sufficient to beat them. With Ange Postecoglou’s team only three points from retaining the league title, second-tier Inverness will sit between Celtic and a fifth domestic treble in seven seasons.
This is an era of Celtic dominance; success in that Scottish Cup final early next month will take the club’s recent trophy count to 17 from a possible 21. Rangers, whose season is now over in all but name, remain a distant second best to their city rivals.
