Football management moves pretty fast. On Saturday Barry Ferguson was being beaten at home by Motherwell. Five days later he was leading Rangers to a famous victory in Istanbul, responding to being patronised by José Mourinho by ending Fenerbahce’s 18-match unbeaten run.

Perhaps the scoreline wasn’t as eye-catching as the 4-2 win away to Borussia Dortmund three years ago, but given the circumstances this was arguably more remarkable. Where there had been shambles, there was rigour. Where there had been diffidence, there was conviction. Where there had been incoherence, there was incisiveness. This was a result beyond Rangers’ realistic expectations, and yet there was perhaps a frustration that it wasn’t even better.
