Although Irvine feels that he may have won over his doubters, he is wary that the situation can turn very quickly, and believes that he can look no further than the example of Alan Pardew at Newcastle United.
Irvine told Sky Sports News: "No-one is judged on a length of time, we are almost judged game to game. It's a bit sad. People have used the phrase 'the fans were underwhelmed' and I understand all of that. I wasn't going from a position where they had a chance to assess what I was doing and could come to a conclusion.
"I was trying to change people's perceptions from when I came in. I said many times I couldn't control that, all I could do was focus on things I could control. They were waiting to see what could happen. Gradually they have but I'm not naive enough to know what happened to Alan couldn't happen to me.
"It could turn around and if we lose the next four games we are back to where we were. I am pleased for Alan it's turned around, he is a very experienced manager and I felt he would turn it around anyway. I am delighted."
