The 22-year-old is on loan at Newcastle until January, but admits he is keen to make the move permanent in order to get regular football.
Simpson said: “If there was an opportunity for me to stay at Newcastle then of course I would listen, because I’m not sure I would get these opportunities at United.
“I look at someone like Nicky Butt who is a big figure here at Newcastle – he has won medals, played at the highest level and not looked back since he left Manchester United.
“He’s definitely someone I would talk with to get his advice because he’s made a success of his move. I’ve been at United since I was nine and it would be hard to leave, but I’m 22 now and want to play regular football and kick-start my career.”
