"Roy Keane hasn't got the experience and he knows what he's doing. He's different class and he's going right to the top. There's no reason (why) Alan Shearer can't do that as well.
"He'd set the place alight and the fans would love him. You could bring a couple of experienced people in alongside him and it wouldn't be a problem for him.
"Because of what he means to the place and what the fans think of him and what a player he's been, he'd be absolutely perfect. I wouldn't want to see any further than Alan Shearer."
Redknapp went on to dismiss suggestions he had rejected a reputed £5million salary to move to the north-east for any other reasons than his desire to remain at Fratton Park.
Redknapp added: "It was a great opportunity for me to go and manage one of the great football clubs. I understand all that. Some people will say I made the right move and some people will say I should have taken it.
"Everyone's got their own opinions but we all have our own lives. Everybody's got to do what they want to do with their own life, and I love my life.
"I enjoy going to work every day. If I didn't like the place, if I didn't like the owner or if I didn't like the players I'd have been up there like a shot, but there was no need for me to change."
