Alex McLeish insists he has the full backing of the Birmingham board and "doesn't feel at all threatened''
McLeish has led Blues to their first major Wembley cup final in 55 years after a dramatic Carling Cup semi-final triumph over West Ham on Wednesday night.
But acting chairman Peter Pannu questioned the value of some of McLeish's signings at the weekend while there has also been speculation that the manager's position has come under scrutiny.
McLeish accepts it is a results-driven business but is adamant he is working in harmony with the board to bring in new signings before the transfer window shuts on Monday.
He said: "Every job is a challenge and you've got to make the best of it. Let me tell you if I had to leave tomorrow through disillusionment then there would be a queue from here to Glasgow wanting my job. But I cherish this job and I want to make the best of it and I don't want to fail.
"Obviously you need a bit of help in terms of everything - support from the fans and the board. We're all in it together. We've all got to help each other and that's what's happening and I'm getting good support.''
McLeish added: "Listen, it's a results-driven business. You are probably the same in your job. You probably have to keep delivering. If you don't, your bosses will look at you.
"It's about results and, at the end of the day, the manager is the most important person because, when things go wrong, he is the person that gets fired. I'm aware of the challenges but I've been aware of that for a long, long time having managed Scotland and Rangers where you are one game away from a crisis. I've got experience and expectation levels.
"I don't think buying me time here has ever been in question. I don't feel at all threatened. I see everything as a challenge. I don't see anything as a threat. I'm privilege to be involved in the game at this level and I want to go even higher in the game. It is a great challenges ahead but I don't feel under any threat.''
