The Magpies finally secured their top-flight status with a 2-0 victory over West Ham at St James' Park on Sunday, their first win since February 28 and just the third of Carver's 19-game league reign.
But their fate remained in the balance until Jonas Gutierrez's 85th-minute strike settled the nerves among a crowd of 52,094 at St James' Park, and head coach Carver knows that is simply not good enough.
He said: "I do know Mike even did an interview beforehand - I didn't see it, but that's the step that we might be taking to bring this football club together, because it has to be one, it has to be one for us to be successful.
"We can't afford to get ourselves in this situation ever again. We all know we have made mistakes, everybody, and we have admitted those mistakes.
"This is a big summer now and I have had assurances that we are going to spend money, so the fans can now go away, have their summer holidays, look forward to players coming through the door, but also look forward to that fixture list coming through.
"It feels like you have just won the cup, that's what it feels like. I actually sit here now feeling like I have won the cup, and wouldn't it be great in the future to be sitting here having won a cup?
"Now I know Mike has come out and said he wants to win things and he is going nowhere. Well that's a good thing, that's a good thing as long as we get everybody together, Mike, (managing director) Lee (Charnley), myself, whoever it is - me, because I want this job, by the way, so there's another story for you.
"I am not going anywhere unless they tell me I am going somewhere else, but I want this job."
