The United youngster is currently on a season long loan to Blackburn Rovers.
“You need experience,” Simpson told Sky Sports News.
“You need Sir Alex Ferguson to trust you that you can cut it in the Prem.
“For me, at the moment, I want to get as many games as I can.
“Obviously I will go back next season and then have a meeting and see what he says.”
Ferguson has claimed he is not interested in selling the 21-year-old defender.
Simpson added: “Obviously, it’s what everyone wants to hear that I’m still in his plans and while I’m not there it’s nice to hear.”
