Last season, Duffy clocked up 18 games for Scunthorpe in League One and now he says he is ready for the Championship.
He admitted to the Irish Sun: "I'm dying to get out really.
"The manager knows what he's doing with me. Hopefully he can get me something sorted.
"Even if I'm staying with Everton, he says I'm not far off.
"I went to League One when I was 19. I think I'm ready now for just below the Premier League."
