There has been a fresh outbreak of off-field unrest at the Glasgow giants this week -and disgruntled fans have threatened to withold season ticket money this summer.
The move came after it emerged last week that two investors - Sandy Easdale and Laxey Partners - agreed to lend the SPFL League One leaders £1.5million.
The fact the loan is secured on Edmiston House and the Albion car park facilities has not gone down well with supporters.
Nor has the fact that Laxey Partners, the biggest single shareholders in the club, stand to make a £150,000 profit when their cash is repaid in September.
The Union of Fans - an umbrella group comprising six supporters organisations - intends to pool season ticket money into a trust.
Dave King, the former director and wealthy South African businessman, has urged them to release the cash on a "pay-as-they-play" basis when their demands are met.
It is the latest in a long line of off-field disputes to erupt at Ibrox during the last few years.
But McCoist is confident his players have grown well used to speculation and uncertainty about their future.
The Gers, who take on East Fife at New Bayview this afternoon, could complete Stage Two of "The Journey" by winning the third tier title this month.
On top of that, they are still involved in the Ramsdens Cup and the William Hill Scottish Cup.
And their manager has predicted their efforts in all three competitions will not be affected by the stand-off between the club board and their customers.
McCoist said: "We are really fortunate to have a great set of professionals who are 100% focused on the football side.
"It would be understandable for them to look at outside factors which are not ideal.
"But we have a great set of older pros and a mature set of younger boys. They don't let anything get in the way of them concentrating on their football.
"I'm very confident that they will handle it. Once they cross the line and go on to the park they do their jobs. That's when they're at home. That's what they want to do.
"That's why they keep training well. That's why they keep turning up and getting results and I am sure they will continue to do that."
McCoiste intends to concentrate solely on what he is employed at Rangers to do - manage the football team - and not get involved in off-field matters.
The record Rangers goalscorer has been in an impossible position as the stand-off between supporters and the board of director has intensified.
However, he is working behind the scenes on a daily basis with chief executive Graham Wallace and others to return the Ibrox club to the forefront of Scottish football.
McCoist said: "The fans have always supported the club. They're great and they will continue to do that, I would think.
"My only concern over the next 24 hours is us going to East Fife and getting a result. I think people can appreciate my need for silence on this whole thing.
"I have been pretty open in terms of discussing everything really, but I think that, at this particular time, I just need to take a step back.
"I want to let the fans know that the footballing side of things hopefully is in good hands with the staff and the players and what will be will be."
He continued: "The best thing that we can do is get the fans three points because effectively that is still the most important thing in all the fans' eyes.
"They want to see the team winning, they want to see the team progressing, they want to see the team going back up the leagues. It might seem a small thing to outsiders, but it's the one thing that we can have a big bearing on and that's what we aim to do.
"I have made a conscious decision that I'm going concentrate on football. It's easy to separate the football from the other stuff, because that's my job.
"For one reason or another, I've had to deal with the other side of things. But the football side is my job and what I get paid for."
