But Sheridan believes his protege still has plenty to learn, and is not shy in telling him so.
He told the Manchester Evening News: "I had Deane in the youth team and the reserves, and I love him as a kid - he's a lovely lad. He knows that I believe in him, and that's all I can do.
"But I will pester him and moan at him, because that's the way I am.
I want him to be a player, and that's the reason I do keep on at him. He definitely can be a player, but he has to have belief in himself."
