Sir Alex’s comments came after Powell scored with a shot from distance on his United debut against Wigan last week, reminiscent of the 37-year-old playmaker.
But Powell recognises that he has a lot of hard work ahead of him before he can even begin to think about replacing Scholes.

"For someone like him to say he thinks you can do that is amazing to hear," Powell told United Review.
"The expectations of you are there, but it's fulfilling those expectations which is the challenge, especially when you consider that there will probably never be another Scholes.
"What he has achieved in his career is more than most people can dream of - to achieve even half of what he has would be brilliant. Hopefully I'm on the right path."
Powell could make his first competitive start tonight against Newcastle United in the League Cup, with the 70-year-old Ferguson expected to give some of his younger stars a chance to shine.
"It'll be a great experience for whoever is playing this evening and a tough challenge," Powell added. "If I'm involved, I hope it's one I can rise to. If I get my chance, I'm determined to take it with both hands.
"It will definitely be a good test for us. Newcastle did really well last year and were pushing for a top-four place. They're a good side."
