Speculation has been rife that the pair could work together, but Shearer says he has had no contact, and he is not sure he wants the job of "number two".
In an interview with BBC1's Look North programme on Thursday night, he said: "I haven't considered it - I haven't had anything to consider, to be honest.
Shearer Comments Could Ruin His Toon Chances!
"He is his own man. As I said, I have got tremendous respect for him. I worked with him as a player at Newcastle and with England.
"I am sure he will do well and whoever he brings in, if anyone, it will be for the benefit of the football club.
"First and foremost, I don't know whether Kevin wants me as his number two, and I don't know whether I want to be a number two.
"He hasn't been in the job very long. He needs to go into the football club and have a look around and see what he needs, whether he needs to bring his own people in or stick with the people who are already there.
"But if he was to ring me, then of course I would speak to him because I have great respect for him.
"I'm delighted. I was as surprised as a lot of people.
"What he will bring is tremendous enthusiasm, great commitment, and I think he will just bring a spark to the area.
"You have seen the reaction to the game yesterday evening - that's what he has on the area.
"He knows the football club, he knows the people, he knows what they want and he knows that they want a style of play there, they want to be entertained.
"He certainly did that last time he was manager and I am positive he will do the same again."
