Ryan Jack and the Rangers reaction I can't suss out as Ange style addiction absent at Ibrox - Hugh Keevins

In Ange We Trust is the Celtic fans’ slogan of support for their manager.

The Prophet Postecoglou, they implicitly believe, will eventually lead them out of the wilderness that was last season and give them back the league title.

The question is, has everyone associated with Rangers bought into Giovanni van Bronckhorst in the same non-negotiable way?

I can’t make up my mind whether the look on Ryan Jack’s face when he was hooked in Braga on Thursday night was frustration borne of disappointment or good old-fashioned anger.

I don’t know whether he was being diplomatic or not when he spoke about an injury afterwards but he looked about as happy as the average Rangers supporter when they bring up the 12-point swing in Celtic’s favour that has befallen Rangers on the manager’s watch.

Celtic remain seven games away from a possible domestic Treble that would test the credulity of their most terminally-optimistic supporter, given where they were at the start of the season.

Rangers look as if they’re still suffering from the after-effects of losing to their rivals last Sunday.

Any Rangers or Celtic manager is only ever three games away from a crisis.
