Ally McCoist is on the rack after Alloa shock Rangers
They have stood by him during extremely difficult times, but Rangers fans are now calling for Ally McCoist's head.
McCoist ran the gauntlet of abuse after little Alloa beat the Gers for the first time in their history - and after being two goals down too.
There looked to be little danger of an upset when the Glasgow giants took a comfotable lead through Kenny Millar and Northern Ireland international Dean Shiels in the Petrofac Training Cup semi-final at Alloa's Indodrill Stadium. But the minnows stormed back via Greig Spence and Ryan McCord.
And Gers fans couldn't believe it when Spence found the winner on 89 minutes to set up a final date with Livingstone.
McCoist (left), who has been in the managerial hotseat since 2011, was already under pressure after Rangers fell nine points behind promotion rivals Hearts in the Championship.
But the man who, as a player, was one of Rangers' most popular servants, insisted after the game that he wouldn't quit.
"I share the fans' disappointment but there is a long way to go in the season and we'll fight to get the club back where it be belongs," he said.
McCoist has presided over a stack of mortifying losses during his three-and-a-half year reign as boss.
But the Indodrill Stadium disaster is easily his worst and puts his future in grave doubt.
The 52-year-old hit out at his players' lack of professionalism but insists he will not give in to the fans questioning his leadership.
Asked if he was considering resignation, he said: "No I'm too concentrated on the game here.
"My decision is to look at the performance tonight, particularly after we went 2-0 up, then sit down with the boys and go through it.
"It won't be a pleasant meeting but it has to be done and it will be done."
He added: "The fans are entitled to a few choice comments."
This was the third time the teams have met this season but a Wasps side made up of workmen and office workers have yet to be beaten.
For all his meagre resources, Barry Smith saw his Alloa squad decimated even further with illness and injury counting out nine senior players.
But McCoist's expensively-assembled Rangers side - who have beaten Premiership opposition three times this season, including Kilmarnock on Sunday - toiled.
They went ahead though as Miller scored off the rebound from a Kris Boyd free-kick before Shiels finished tidily for the second.
That should have been enough for the win but Spence was allowed to pull one back before McCord made it two goals in three minutes as Rangers switched off completely. And they were still sleeping as Spence slotted home the winner in the final minute.
"We got what we deserved," said McCoist. "We took our eye of the ball and lost some really sloppy goals.
"We were aware how difficult it would be after coming here earlier in the season and them holding us to a 1-1 draw. They then hit us with a late equaliser at Ibrox.
"It is not as if we didn't know what to expect. But the real disappointing thing is that after being 2-0 up we couldn't see the game out.
"I didn't say an awful lot after the game - I will save that for the next few days. I'm not sure if there was a lack of character but there was certainly a lack of professionalism to see the game out from a great position. We should be able to see the game out.
"We switched off at a couple of crosses. We lost men at attacks, we turned our back on set-plays. They were allowed to take a quick throw for the second.
"It's about professionalism - taking responsibility to do your job."
Smith said: "It's a massive achievement for the club, the players and myself.
"I thought we were excellent in the first half but to come from 2-0 down to win 3-2 was exceptional.
"We had nine players missing but the boys who came in were excellent.
"It's massive for the club to get to a cup final - and to put Rangers out on the way there. It's great to be the first Alloa manager to beat Rangers."
