They support the view the 39-year-old is Rangers’ worst ever manager.

Albeit over a 123-day period, the shortest tenure of any first-team boss at Ibrox, Martin’s 29% win percentage is the lowest in the club’s history.

Paul le Guen managed 52% and Pedro Caixinha’s was 54%. Even Barry Ferguson’s interim spell had a win rate of 40%. Graeme Murty’s was 60% across his two caretaker stints. Clement (64%) and Beale (72%) are well clear.

As for Martin, it felt like each game came with a new low.

A 1-1 draw with Dundee in his second Premiership game marked the first time since 1989 that Rangers had failed to win their opening two league fixtures.

Losing to Hearts in September meant the Ibrox side had not won any of their first five league matches for the first time since 1978.

A 6-0 humiliation in Brugge, inflicting a 9-1 aggregate embarrassment, was a record-equalling European defeat.

And the 2-1 Europa League loss to Sturm Graz on Thursday ensured Rangers went a 23rd consecutive away game without a clean sheet. That is a new club record.

Even in victory there were serious red flags. Martin’s side faced an eye-watering 73 shots across four matches while progressing past Panathinaikos and Viktoria Plzen in Champions League qualifying.

The underlying numbers told us it was not sustainable. And so it proved.

In the Premiership, only two teams have scored fewer goals than Rangers this term. No team has had fewer clean sheets. They have only faced two shots fewer than St Mirren. They are on a negative goal difference.

Their expected goals (xG) rating of nine ranks them eighth, where they happen to be placed in the standings that really count.

Even with that evidence, Martin often said his team’s deficiencies were down to mentality issues and not tactics.

In the backdrop, Rangers’ board sanctioned a net spend of around £20m in the summer window. There have been suggestions that could mean the club spent close to £40m on incomings.

For context, that is an astronomical figure for a Scottish club.
