Glasgow Rangers: Ally McCoist vows to fight on
Against the odds, The Wasps stormed back from two goals down with just 17 minutes remaining to set up a Petrofac Training Cup final with Livingston.
McCoist hit out at his players' lack of professionalism but insists he will not give in to fans questioning his future.
Asked if he was considering resignation, he said: "No, I'm too concentrated on the game here."
He added: "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."
McCoist became Rangers' 13th manager when he replaced Walter Smith in 2011.
The 52-year-old former Gers striker led the club to the consecutive promotions to the second flight, but they are nine points off leaders Hearts this season.
